I do install test Centrals on a more or less regular basis :) and yes  
the procedure can be... challenging :). Especially since we try to  
keep the OS and other software separated. So we never install stuff  
in the "default" place. I have no experience with the latest pure  
Perl version of BioMOBY Central, but libxml2 should be fine as long  
as you have a relative recent version. Not sure if this helps, but  
from my own experience:

* For older versions there is a list describing which version of  
XML::LibXML works with which version of libxml2. Apparently you can  
not randomly mix versions! Even minor differences in the version  
number can break things.

* If libxml2 is not in the default path or you have an OS supplied  
older version in the default path and want to link some Perl stuff to  
a newer version in an alternative location, please make sure the xml2- 
config binary is pointing to the libxml2 version you want to use and  
xml2-config is in your PATH both for yourself and for the apache user.

If you are having other problems just put them on the mailinglist;  
maybe one of us has seen them before...

I'd love to give that one a try, so if you are looking for a "guinea  
pig" let me know :)...
