Thanks, but I need a little further advice.

I am using Python under Window 98 on this machine.

I followed the long trail of needed software and downloaded something
called CyqWin. This resides at c:\cyqwin on this machine. It put a
desktop link that runs a bash shell and the gcc compiler seems to be
known. The only problem is I now have two versions of Python 2.1 ---
one at C:\cyqwin\python and one at C:\Python21 --- but this is no big

I also have something called cln at c:\cyqwin\cln\cln-1.1.tar.gz
and ginac at c:\cyqwin\ginac\ginac-0.8.3.tar.bz2.tar (yes! two tars in
that one)

I also have an animal named pyginac at

So, how do I unpack tar/bz2/gz ? Suppose cyqwin has the software there

After it is unpacked --- what in the world do I do with it to get
pyginac to work with my Python21 IDLE interface??

Any comment would be greatly appreciated.

Regards, Joe
