PG compilation

Hi,

I would like to know if there is a way to pass an argument to ./configure
to consider compiling with a specific python version ? coz i have many python versions in the system .I presume that
configurewould check for the /usr/bin/python alone, but what if i want /usr/bin/python2.5 to be compiled in ?  

regards ,
KM

ya had looked at '--with-python' option but that is where my question arises - it looks at default python
(/usr/bin/python)and not /usr/local/bin/python2.5 which i need for PL/Python functionality in PG 8.2.1 
one solution is to soft link the /usr/bin/python to /usr/local/bin/python2.5 but i donot want to change the default
pythonon the system as some other programs depend on it. 
so i am looking for a flexibility in configuring PG that it created python modules  with python2.5 only.
any ideas ?

regards,
KM

ya extracted the object file.

ya it says :

abstract.o: ELF 64-bit LSB relocatable, AMD x86-64, version 1 (SYSV), not stripped

I had installed python2.5 myself from source package.
