#67780: gwyddion @2.63: opportunistic use of other ports
------------------------+----------------------
 Reporter:  ryandesign  |      Owner:  rowue
     Type:  defect      |     Status:  assigned
 Priority:  Normal      |  Milestone:
Component:  ports       |    Version:  2.8.1
 Keywords:              |       Port:  gwyddion
------------------------+----------------------
 gwyddion searches for several programs and libraries that exist in
 MacPorts but are not declared as dependencies of the port:

 {{{
 :info:configure checking for update-desktop-database... no
 }}}
 {{{
 :info:configure checking for inkscape... no
 :info:configure checking for pngcrush... no
 }}}
 {{{
 :info:configure checking for MINIZIP1... no
 }}}
 {{{
 :info:configure checking for WEBP... no
 }}}
 {{{
 :info:configure checking for EXR... no
 :info:configure checking for h5cc... no
 :info:configure checking for HDF5 libraries... no
 :info:configure configure: WARNING: Unable to locate HDF5 compilation
 helper script 'h5cc'.
 :info:configure Please specify --with-hdf5=<LOCATION> as the full path to
 h5cc.
 :info:configure HDF5 support is being disabled (equivalent to --with-
 hdf5=no).
 :info:configure checking for CFITSIO... no
 }}}
 {{{
 :info:configure checking for JANSSON... no
 }}}
 {{{
 :info:configure checking for msgfmt... no
 :info:configure checking for gmsgfmt... :
 :info:configure checking for xgettext... no
 :info:configure checking for msgmerge... no
 }}}

 If the user happens to have the ports that provide any of these features
 installed, it looks like gwyddion will try to use them. This makes the
 gwyddion build non-[ReproducibleBuilds reproducible]. For each of these,
 gwyddion should either declare the dependency or add a configure flag to
 tell the build not to use it even if it is installed.
