Configure/Build 9.0 rc1 - cannot build against python3.1, with two versions of python in the environment

[Release]: 9.0 RC1

[Test Type]: Install (Build)

[Test]: Configure/Build 9.0 rc1 - cannot build against python3.1, with two versions of python in the environment

[Platform]: Solaris 10 Sparc E450 Quad

[Parameters]: 

--with-includes=/usr/local/include/python3.1:/usr/local/include:/usr/local/ssl/include \

--with-libraries=/usr/local/lib/python3.1:/usr/local/lib:/usr/local/ssl/lib \

CONFIGURE OUTPUT: -----------------------------------------

checking for python... /usr/bin/python

checking Python configuration directory... /usr/lib/python2.4/config

checking how to link an embedded Python application... -L/usr/lib -lpython2.4 -lresolv -lsocket -lnsl -lrt -ldl -lm

configure: using CPPFLAGS= -I/usr/local/include/libxml2  -I/usr/local/include/python3.1 -I/usr/local/include -I/usr/local/ssl/include

configure: using LDFLAGS= -L/usr/local/lib  -L/usr/local/lib/python3.1

[Failure]: Can't seem to definitively config PG to a specific version of python - v3.1, at /usr/local/bin/python3

[Results]: configure seems to pick up python 2.4 configuration, but apparently links to (desired) python 3.1 libs.

[Comments]: Tried first to see if configure picks up the PYTHONPATH env variable to find python's configuration.  No joy.  Using this variable might be a reasonable approach for configure?
