CentOS - libxml and libxslt missmatch

[Geoff Shang]

Hello,

First, apologies for misspelling CentOS.

I'm doing some work for a client who wants Icecast installed.  The closest 
thing I could find was an official srpm on icecast.org, but I've hit a 
problem.

I'm getting the following error when trying to build the rpm:

/usr/lib/libxslt.so: undefined reference to `xmlXPathContextSetCache'

According to 
http://icecast.imux.net/viewtopic.php?t=6802&sid=b654f97be93fc2aeb1874c9320f23214 
this is caused by a missmatch between libxml (2.6.26) and libxslt 
(1.1.17).

Anyone know how I can solve this without compiling from source?  I'dve 
thought there'd have ben an upstream fix for this by now but don't now how 
to check for it since I'm clearly not a CentOS expert.

Cheers,
Geoff.
