Could someone advise me on a fix for my compiler

Question

I have Xcode installed with both gcc-3.3 and gcc-4.0.1... BUT... i think that there is another version (gcc-4.1.1) floating around that I must have inadvertantly (or advertantly, but long enough ago that I don't remember doing it) installed through wither Fink or Darwinports. i THINK that it happened when i installed GHDL tools through Bertram's port to Darwin... which I have since "removed", but $sudo "gcc -v" says:
+Using built-in specs.+
+Target: i386-apple-darwin8.6.2+
+Configured with: /Users/fbertram/Documents/eng-osx/GHDL/gcc-4.1.1/configure --enable-languages=vhdl --disable-nls --disable-libssp --prefix=/Developer/Simulator/GHDL+
+Thread model: posix+
+gcc version 4.1.1+
i tried "sudo /usr/sbin/gcc_select 3.3" and "sudo gcc_select 3.3", but "gcc -v" still says the same as above. I checked by "echo $PATH" and I get:
/opt/local/bin:/opt/local/sbin:/sw/bin:/sw/sbin:/bin:/sbin:/usr/bin:/usr/sbin:/u sr/X11R6/bin
Which looks OK. I am asking this because my builds are failing in strange ways lately, and I fear that they may be reading from the gcc 4.1.1. I tried uninstalling gcc-4.1.1 through fink and darwinports, but the program does not show up as being installed.
Anyone know what is going on here? it would be nice if there were a "dpkg-reconfigure gcc" function that I could use in OSX... I tried deleting Xcode and reinstalling from the CD ( after running uninstall-devtools.pl from the terminal) but there is no change.
HELP!

Hello,
Try "gcc_select -l" to see all available versions of gcc.
Try "gcc_select -n 3.3", this will show you the command gcc_select WOULD USE to make the change, without doing it. Check if it makes sense...
try "which gcc", this will give you the path for the first gcc in your path. Mine is in /usr/bin/gcc.
Now, cd to that directory (/usr/bin for me), and do "ls -ld gcc*". You should see gcc as a link to something like gcc-3.3 or gcc-4.0 .
Also, look at the compile log within XCode (build results). It might tell you which version of gcc it's using.
If XCode fails to compile even the simplest "Hello, world" program, try compiling it manually by invoking "/usr/bin/gcc-3.3 hello.c" from the source file's directory. You would get an executable called a.out that you can execute with "./a.out".
Good luck,
