Solaris 10 + Sun Studio 12 Pyrhon 2.4.4 64-bit build problem

[MrJean1]

Here is a better way to build Python on Solaris, both 32- and 64-
bit.

 <http://ccnuma.anu.edu.au/~wpc/blog/programming/building-python.html>

since it builds both the binary and make test on my Ultra 20 machine.
In my case 26 tests pass, 1 failed, 44 are skipped and there are 6 u
expected skips.  The latter are expected and due to missing packages,
like Tcl.

Use the instructions from this site and forget mine.  But it may still
be necessary to patch the ./Include/pyport.h file as shown in my
previous message.
