Hi Andrew,

It appears that you have become the victim of the classic "devel"
packages snare.  Basically, any time you wish to compile something
against an RPM package on Mandrake, RedHat, RedFlag, and other RedHat
derivatives, you need to also get the "devel" version of the package.

All you need to do is grab the python-devel-2.1.1-3mdk.i586.rpm and
install it also.  You can find more information on what this RPM has at:

http://rpmfind.net//linux/RPM/mandrake/8.1/i586/Mandrake/RPMS/python-devel-2.1.1-3mdk.i586.html


Hope that helps.

Zed

P.S., It might be a good thing for you to setup a "cooker" source so you
can do urpmi and automagically install these things.  Contact me off
list if you are interested in setting this up.  It's fairly easy.
