>Description:
	Various ports (mainly the ones running xmlto, like xmlto itself or gpsd) fail to build because of a failure in xmlto. The problem comes from /usr/local/bin/xsltproc. It fails to correctly process xslt correctly. 
For the case of gpsd, the message from xmlto is :
echo 'timestamp for stamp-gps-manpages' > 'stamp-gps-manpages.tmp' &&  xmlto  man './gps.xml' &&  mv -f 'stamp-gps-manpages.tmp' 'stamp-gps-manpages'
warning: failed to load external entity "http://docbook.sourceforge.net/release/xsl/current/manpages/docbook.xsl"
compilation error: file /tmp/xmlto-xsl.yBIWLy line 4 element import
xsl:import : unable to load http://docbook.sourceforge.net/release/xsl/current/manpages/docbook.xsl
*** Error code 1

By debugging i got that far:

The problem is that a huge number of ports depend on this, so practically a system with KDE or gnome cannot be upgraded.
>How-To-Repeat:
	Try to install astro/gpsd or textproc/xmlto
