 I cannot remember what the symptoms of the problems with openjpeg and
 openmp were. I guess I saw errors mentioning these packages/header files.

 I thought I solved the openjpeg problem in leptonica as described in
 https://trac.macports.org/ticket/55283.

 In my shell history I also see that I did
 {{{cp /usr/local/lib/pkgconfig/lept.pc ./lib/pkgconfig/}}}. I don't
 remember the reason for this.
 Trying to solve the error with openmp I did (as root) make a symlink in
 /opt/local/include/clang to omp.h:
 {{{
 pushd /opt/local/include/
 mkdir clang
 cd clang
 ln -s /usr/local//Cellar/llvm/5.0.0/lib/clang/5.0.0/include/omp.h omp.h
 }}}
