Comment (by giovannicantele):

 Thank you a lot for you prompt message.Unfortunately, after following the
 suggested steps ( uninstall + clean + install with variant), exactly the
 same error shows up:

 {{{

 '/usr/lib/libgfortran.5.dylib' (no such file)
 }}}

 However, after a closer and deep inspection, I realised that xcrysden (or
 maybe any other code needing libgfortran) looks fo that library in
 standard paths, such as /opt/local/lib . On the other hand, the output of
 the command
 {{{
 port contents libgcc-devel | grep gfort
 }}}
 is
 {{{
 /opt/local/lib/libgcc/libgfortran.5.dylib
 }}}

 That means that libgcc-devel puts libgfortran.5.dylib in a non-standard
 path (under libgcc under lib), that causes the issue. This is probably a
 bug or an issue, in any case.
 After

 {{{
 cd /opt/local/lib
 sudo ln -s libgcc/libgfortran.5.dylib .
 }}}

 everything works fine.
