First PKGBUILD, Faulty when Installed by Pacman?

Question

I'm trying to package this:
Enigma-dev (git)
http://enigma-dev.org/
I'm having a problem with it when it gets installed by pacman, where it tries to compile itself again..
PKGBUILD:

cd "${srcdir}/${pkgname}"
make
pkgver () {
# this doesn't really work because pkgver is executed before build, so there is no local repo. and there is no apparent way to get remote revision numbers if there are no tags..
# I tried cloning the repo here instead of in build, but that didn't work either.. so basically this only returns anything useful if you try and install it twice.

based of these installation directions:
http://enigma-dev.org/docs/Wiki/Install:Git
(which I have followed and work fine)
For one thing, there doesn't seem to be a install target for make, so I just copied the whole thing into /usr/share/ 
My main problem is that normally the compilation is handeld by the java lateralgm program the first time it's run, though just running make works fine.
until pacman installs it, that is.
It still works after being copied, I can run it in $srcdir/enigma-dev-git/ ,
but when I try and run it both by just running lateralgm and cd ing to /usr/share/enigma-dev-git/ then java -jar lgm16b4.jar it will try and compile enigma like it never was compiled in the first place (of course, it can't because it doesn't have root permissions)..
I didn't see any diference in the permissions between $srcdir/enigma-dev-git/ and /usr/share/enigma-dev-git.
I even tried having it install into ~/ with pacman just to see what happened but same thing..
However, I can copy the contence of $srcdir to ~/ and it will work..
Anyone know what might be the issue? (or how to improve anything else?)
Thanks

Have you tried simply dumping the whole thing to opt and putting a script in /usr/bin to run the necessary command? Just what all are you trying to copy to /usr and /usr/bin, anyway? It could very well be as simple as
cd /opt/enigma-dev
java -jar lgm16b4.jar
Of course as Josh @ Dreamland points out, you need to make sure /opt/enigma-dev is world writable.
That is exactly what is going into /usr/bin..
Anyway, I get the same error when trying to run the jarfile directly, so it's  not the /usr/bin script..
As for /usr, it's just all the icons and stuff that is in $srcdir/enigma-dev/packages/linux/usr/share
ah.. so do have to change the permissions of /opt/enigma-dev-git..
I thought that scince it was already compiled it wouldn't have to write anything to /opt/enigma-dev-git.. (I thought that it was lateralgm doing the writing when it compiled enigma, and I didn't have to worry because it already was compiled by then)
I guess I misunderstood, I'm trying it now with permissions.
EDIT:
Seems to work, but is it AUR worthy?
