[FGS] Upgrade version of some packages

[Normand Savard]

All,

In the process to create a new fgs release I modified the following 
package version:

   CURL 7.16.4
   PHP version to 5.2.5.
   Python 2.5.2
   MapServer 5.0.2
   Apache 2.2.8
   mysql 5.0.51a with glibc-23


Does someone see any reason or disavantages in doing so?

Norm
