#64033: gdcm @3.0.5_2: build fails on macOS 12 arm64

     Type:  defect      |     Status:  assigned
 Priority:  Normal      |  Milestone:
Component:  ports       |    Version:  2.7.1
 Keywords:  gdcm xsl    |       Port:  gdcm
------------------------+---------------------------------
 The build fails.  See attached log file.  The only errors I see seem
 related to building man pages.  It seems to have problems accessing some
 external xsl includes or have parsing errors.  I checked a few files and
 could manually access the paths so I do not understand.  Is something
 preventing the accesses?

 I do have port "docbook-xsl-nons" installed which seems to provide many of
 the same xsl includes.  I also have port "libxslt" installed.  I do not
 have similar port "docbook-xsl-ns" installed but could if needed.

 It is curious that the Portfile has variant "docs" commented out with note
 "installation hangs".  I checked CMakeCache.txt and it has

 {{{
 GDCM_DOCUMENTATION:BOOL=OFF
 LIBXSLT_EXSLT_INCLUDE_DIR:PATH=/opt/local/include
 LIBXSLT_EXSLT_LIBRARY:FILEPATH=/opt/local/lib/libexslt.dylib
 LIBXSLT_INCLUDE_DIR:PATH=/opt/local/include
 LIBXSLT_LIBRARY:FILEPATH=/opt/local/lib/libxslt.dylib
 LIBXSLT_XSLTPROC_EXECUTABLE:FILEPATH=/opt/local/bin/xsltproc
 }}}

 Note that port "docbook-xsl-nons" installs *.xsl under
 {{{/opt/local/share/xsl/docbook-xsl-nons}}}
