(exactly the same issue that has just been closed because of the lack of
feedback from the original reporter)

Here is another (old) report referring to the very same issue happening
on Solaris:
http://bugs.python.org/issue1234473
(an issue that doesn't seem to be solved)

I have no idea whether this is a real "Python bug" or not. I'm just
reporting a build "issue" that I'm experiencing when trying to compile
python on this particular (non-typical) platform.

So, I have the access to this SunOS machine and the you (the Python
developers) have the knowledge. Let's just work together and try to
discover why the building process is not working out-of-the-box on
SunOS, rather that imply that it's not a real python bug.
