Do I understand correctly that you want to compiler numpy/scipy with 
gcc, using sunperf ? I am not familiar with non gnu devtools under 
solaris, so I don't know if sunperf libraries are supposed to work with 
gcc ?

My main guess, though, would be that sunperf requires more than just 
-lblas option to link; generally, you need some other link flags. Since 
the default error message of the linker is non explanatory, we need more 
info. What does nm 
/local/cat2/apps-archive/SUNWspro-12/prod/lib/libblas.so returns 
(assuming libblas.so is the name of the library) ?
