[BioPython] Installation problem on debian

[Pieter Laeremans]

Hi,

When I'm trying to install biopython on a debian system (sarge), with
python2.3 and all the dependencies installed.

But I get this error:

/tmp/biopython-1.24 $ python setup.py build

So I think there has to be a library 'fl' whIch has to be installed.
But I don't know which librarh it is. Has someone succeeded in
installing this software on a debian system?

Thanks, 

Pieter
