Petulant buildbots

[Craig Treleaven]

Ok, so I’m sure the buildbots aren’t exactly being “petulant” but…

I’ve updated mkvtoolnix to 13.0.0. On my main system (OS X 10.10, Xcode 7.2.1) it builds and runs without issue.  Building in trace mode did not work so I’ve fired up a 10.9 VM and did a virgin build.  That completed and runs successfully as long as MacPorts clang-3.7 is used (as the port needs C++14 features).

However, none of the buildbots have ever succeeded in building this port.  The 10.9, 10.10, 10.11 and 10.12 buildbots all fail to configure with the following message:

checking whether xsltproc works... no
configure: error: xsltproc doesn't work with DocBook's /opt/local/share/xsl/docbook-xsl//manpages/docbook.xsl
Command failed:  cd "/opt/local/var/macports/build/_opt_bblocal_var_buildworker_ports_build_ports_multimedia_mkvtoolnix/mkvtoolnix/work/mkvtoolnix-13.0.0" && ./configure --prefix=/opt/local --mandir=/opt/local/share/man --with-boost=/opt/local --with-extra-libs=/opt/local/lib --with-extra-includes=/opt/local/include --with-xsltproc=/opt/local/bin/xsltproc --with-docbook-xsl-root=/opt/local/share/xsl/docbook-xsl/ --with-po4a=/opt/local/bin/po4a --with-po4a-translate=/opt/local/bin/po4a-translate --enable-qt --with-qmake=/opt/local/libexec/qt5/bin/qmake --with-moc=/opt/local/libexec/qt5/bin/moc --with-uic=/opt/local/libexec/qt5/bin/uic --with-rcc=/opt/local/libexec/qt5/bin/rcc 
Exit code: 1


My local 10.9 and 10.10 builds have never complained about xsltproc.  

Any suggestions on why on the buildbots are not cooperating with me?  Ideas how to appease them?
