With PHP (5.2.17 and 5.3.8) built for LiteSpeed using libxml 2.7.8 and libxslt 1.2.6, scripts attempting to use the XSL support display a 503 forbidden error page. The following shows up in stderr.log: 2011-10-10 13:41:17.711 [STDERR] lsphp5test:<snip>: symbol lookup error: /opt/xslt/lib/libxslt.so.1: undefined symbol: xmlXPathCompiledEvalToBoolean The exact same build / versions work just fine with Apache suphp. Downgrading libxml to 2.7.7 and rebuilding libxslt to use this older version addresses this problem with LiteSpeed. We need a fix for this with LiteSpeed and libxml 2.7.8. EasyApache uses 2.7.8 in its current builds so this is likely to be a widespread problem for those rebuilding PHP based on libraries built by EasyApache. Please advise.
