BUG: docbook2X attempts and fails to load "http://docbook2x.sf.net/latest/xslt/man/docbook.xsl"
Using the docbook2man utility provided by docbook2X, I encountered problems about fetching external entity "http://docbook2x.sf.net/latest/xslt/man/docbook.xsl". However, the docbook.xsl file is installed by the port. I hence modified the portfile to replace the place referring to http for it to refer to ${prefix}. Plus after that I got an error about "${prefix}/share/docbook2X/charmaps/roff.charmap" not being accessible, hence the explicit reinplace of \${prefix} to ${prefix}.
Committed. Thanks!
