Installation problem: Python 2.5 on solaris 8

[Venkat]

I am very new to Python. I installed Python in Windows and learning
it. But i need to install Python on Solaris 8 to automate few things
as my build environment is on Solaris. When i tried to download python
2.5 source code and tried to compile i got the error saying
"configure: error: cannot compute sizeof (int), 77".

Between i am also getting parse errors for few files including
siginfo.h
