Description Justin Bull 2009-06-13 09:46:43 UTC 
Description of problem:
libxslt appears to be referring to a non-existent feature in libxml2 during compile time of Icecast2's source RPM. According to the Icecast2 developer, this may have to do with version mismatching from the repositories. At the time of this writing, both libraries are stock from CentOS Repos, updated, and are the -devel packages.

Version-Release number of selected component (if applicable):
libxml2-devel - 2.6.26-2.1.2.7.x86_64
libxslt-devel - 1.1.17-2.el5_2.2.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Download icecast-2.3.2-0.src.rpm (latest at time of writing) from icecast.org
2. Build source RPM
  
Actual results:
/usr/lib64/libxslt.so: undefined reference to `xmlXPathContextSetCache'

Expected results:
Make OK

Additional info:
Minimal research shows all who have encountered this issue have been unable to resolve it and run CentOS 5.3 x64 machines.

  the cache was added in 2.6.26 (25 actually) version of libxml2.
It's being used in libxslt from 1.1.17, both released on June 6 2006

 the problem is either in your build or your setup, not in RHEL-5.3
