Solaris compiler environment trampled by GNUs

[pkg PBE-SIT]

(short version: I need references for howto setup a compiler environment for 
samba/gcc for solaris 2.6)

My poor solaris machine.

I have a sun 
- sparc machine with 
- solaris 2.6 and a 
- binary version of Samba 2.0.7.

I have tried to get a good and thouroghly compiled 2.2.2 version going, but with all 
my gazillion attempts at downloading GNU supportfiles, gcc versions (source and 
binary), binutils, make-programs and yada yada it fails every time.  

Now I have surely messed up all libs and includes and whatnots into oblivion.  

My question is therefore:   Where do I find a GNU-bie-fied walkthrough of setting up 
a compiler environment (with gcc preferable) for Solaris 2.6?

More specific: where do I find the libraries (supportfiles) to compile the compiler?

Regards
Per Kjetil Grotnes

Note: The binary GCC versions would not compile itself in source.
