Did you end up finding a solution on this? I assume you've tried reinstalling and/or updating Slic3r already, right? +1 for having to mention XML onto this list, which I never expected....

The slic3r software is written in Perl, a programming language that can be expanded with local libraries. XML::SAX is one such library. CPAN is a tool which can be used to retrieve libraries from the CPAN repository (Comprehensive Perl Archive Network, I believe).

I use CPAN is something I do infrequently, so I would be doing a disservice by trying to list the steps here. Better answers are, no doubt, on stackexchange. Nevertheless, these may help:

From your command line, start Perl running the CPAN module, and invoke the CPAN shell (your input in **bold**):

> **perl -MCPAN -e shell**  
cpan> **install XML::SAX**  
cpan> ... several lines of output ...  
Done!  
XML::SAX is up to date (0.99).  
cpan> **quit**  
>

With that done, try using slic3r again.
