Solaris-2.8: Error gcc-3.0.1 iso/math_iso.h

[Jackson]

Greetings -- 
I installed gcc-3.0.1 form freesunsoftware.com and am getting
the following error whenc trying to compile/install a package
( In this case a python module), is there around this problem?
Platform: E6500 Solaris-2.8

Thanks for your time.
