This problem is apparently caused by missing a file (CS/plugins/aws/skinlex.cpp).  I was able to fix the problem by downloading the missing file from CrystalSpace\'s CVS.
Here is a link to the missing file on the SourceForge Web frontend:

http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/crystal/CS/plugins/aws/skinlex.cpp

Click \"(download)\" and save the link to disk in the appropriate directory.  As of today, the newest version on the CVS is the same  version that should have been included in the tarball from PS.

It still isn\'t working for me, but the buck has been passed (I think it may just be a question of libraries installed/header files, but it may be impossible to get it to work on my install due to some dependency issues with sarge that have been around for over a month now but no one seems to care)
