Python speed on Solaris 10

I have found that the sunfreeware.com build of Python 2.4.3 for Solaris 
10 is faster than one I can build myself, on the same system. 
sunfreeware.com doesn't bother showing the options they used to 
configure and build the software, so does anyone know what the optimal 
build options are for Solaris 10 (x86)?

Here are some pybench/pystone results, and I include the same comparison 
of Python2.4.3 running on CentOS 4.3 on the same hardware (which is what 
prompted me to find a faster Python build in the first place).

Python 2.4.3:
   System               pybench      Pystone (pystones/s)
--------------------------------------------------------
   Sol10 my build       3836.00 ms   37313.4
   Sol10 sunfreeware    3235.00 ms   43859.6
   CentOS               3569.00 ms   44247.8


My build:
Python 2.4.3 (#1, Oct 15 2006, 16:00:33)
[GCC 3.4.3 (csl-sol210-3_4-branch+sol_rpath)] on sunos5

sunfreeware.com build:
Python 2.4.3 (#1, Jul 31 2006, 05:14:51)
[GCC 3.4.6] on sunos5

My build on CentOS 4.3:
Python 2.4.3 (#1, Jul 19 2006, 17:52:43)
[GCC 3.4.5 20051201 (Red Hat 3.4.5-2)] on linux2


is the difference purely gcc minor version?
