execution fault

[Chris Atwood]

Today I installed rdiff-backup on 4 of my machines, 3 clients and 1 
backup 'server'.  Two of the clients are Mac OS X machines, the other 
client is a x86 gentoo (a linux distro) box.  The server is a ppc 
gentoo machine.

rdiff-backup runs great on all of them except the x86 gentoo box.  I 
get this error whenever I execute rdiff-backup

ImportError: librsync.so.1: cannot open shared object file: No such

*********

Since my two gentoo boxes are very similar I when through looking for 
difference between them.  On both librsync.so files are in the same 
place (/usr/local/lib and 
/usr/lib/python2.2/site-packages/rdiff_backup/_librsync.so), both have 
python 2.2.1, both have librsync 0.9.5.1 installed.  The only 
difference I could find is that my x86 box (the broken machine) had a 
previous install of popt on it (version 1.6.3), and the ppc server did 
not.

So my question is: Is the ImportError above related to the different 
popt verisons? Can rdiff-backup run with a normal popt library?

Thanks for all your help.
