Comment (by juanrgar@…):

 I think I managed to reproduce the issue. Please find attach my failed
 build log.

 If I'm right the install_name of libmozjs-17.0.dylib points to a wrong
 location. In your case it's apparently set to
 ../../../../../../../../../lib/libmozjs-17.0.dylib (in my case it's
 @executable_path/libmozjs-17.0.dylib). The mozjs17 Portfile has a post-
 patch phase that sets the install_name that's going to be used when
 generating the dylib. From your build log I'd say that when you build
 mozjs17, ${prefix} pointed to ../../../../../../../../../

 I'm not sure of this, and I don't know why ${prefix} could possibly point
 to that location. Maybe the fact that your macports tree is under
 /Volumes/ (possibly on an external unit) has something to do with this.
 Anyways, could you please paste here the output of otool -D
 PATH_TO_LIBMOZJS17/libmozjs-17.0.dylib? Could you please also comment on
 where is your macports tree located, and where is your system
 installation?

 To check if I'm right and this is an install_name issue, you could change
 the install_name of your installed libmozjs-17.0.dylib manually, using
 install_name_tool -id PATH_TO_LIBMOZJS17/libmozjs-17.0.dylib
 PATH_TO_LIBMOZJS17/libmozjs-17.0.dylib
