[SOLVED] help with PKGBUILD-svn

Question

I am able to build a python-based package from svn using bash, but am having a problem writing the PKGBUILD.  The bash commands are as follows:
svn co http://svn.berlios.de/svnroot/repos/wsjt/branches/wspr
cd wspr
export PYTHON="/usr/bin/python2"
export F2PY="/usr/bin/python2 f2py.py"
./configure --enable-gfortran --prefix=/usr
make
and this works fine.  Following the ABS PKGBUILD-svn.proto template, I came up with the following PKGBUILD:
pkgname=wspr-svn
pkgver=1
pkgrel=1
pkgdesc="Weak Signal Propagation Reporter"
arch=('any')
url="http://physics.princeton.edu/pulsar/K1JT/wsjt.html"
license=('GPL')
optdepends=('g95')
depends=('python2' 'python-imaging' 'python2-numpy' 'libsamplerate' 'portaudio' 'fftw')
makedepends=('subversion')
_svntrunk="http://svn.berlios.de/svnroot/repos/wsjt/branches/wspr"
_svnmod="wspr"
build() {
export PYTHON="/usr/bin/python2"
export F2PY="/usr/bin/python2 f2py.py"
cd "$srcdir"
if [ -d $_svnmod/.svn ]; then
(cd $_svnmod && svn up -r $pkgver)
else
svn co $_svntrunk --config-dir ./ -r $pkgver $_svnmod
fi
msg "SVN checkout done or server timeout"
msg "Starting make..."
rm -rf "$srcdir/$_svnmod-build"
cp -r "$srcdir/$_svnmod" "$srcdir/$_svnmod-build"
cd "$srcdir/$_svnmod-build"
./configure --prefix=/usr --enable-gfortran
make
but get stuck with the following error:
Found executable /usr/bin/gfortran
error: unknown file type '' (from '-Wl,--hash-style=gnu')
make: *** [WsprMod/w.so] Error 1
Aborting...
I've been googling for hours, but feel like I might be getting in over my head.  I suspect I'm missing something trivial since everything is in place for a successful build.

Thanks for the fast reply Snowman.  You had the right idea.  Although your suggested edit did not work, the following line did:
unset LDFLAGS
I got this from the discussion here:
https://bbs.archlinux.org/viewtopic.php?pid=668971
(Note: in that thread there is an alternative approach suggested by Ranguvar:
export LDFLAGS="${LDFLAGS//-Wl,--as-needed}"
export LDFLAGS="${LDFLAGS//,--as-needed}"
export LDFLAGS="${LDFLAGS//--as-needed}"
which did not work for me.) 
The PKGBUILD concludes with:
package() {
cd "$srcdir/$_svnmod-build"
sudo make DESTDIR="$pkgdir/" install
This runs makepkg -s to completion although I get a warning about a reference to $srcdir.  Performing pacman -U on the tarball installs python files in /usr/lib/python2.7/site-packages/WsprMod and adds wspr.py in /usr/bin/.  Launching the program with python2 wspr.py leads to an immediate segmentation fault.  After the manual build, all the files were in the same directory.  I tried moving everything into the same python directory and still got the seg fault.
When I built manually, I did not have to do a sudo make install.  If I leave out this step in PKGBUILD, however, setup.py does not run and the package doesn't install anything.  So I tried this instead
package() {
cd "$srcdir/$_svnmod-build"
python2 setup.py install --root=$pkgdir/ --optimize=1
which aborts makepkg because of file conflicts.
Can anyone see what I'm doing wrong?
