vigra: "vigra-config --docdir" shows a path in the build directory

[ryandesign (Ryan Carsten Schmidt)]

vigra-config --docdir shows a path in the build directory (which has most likely been deleted by the time the port has been installed):

$ port installed vigra
The following ports are currently installed:
  vigra @1.10.0_0+python27+universal (active)
$ vigra-config --docdir
/opt/local/var/macports/build/_Users_rschmidt_macports_dports_graphics_vigra/vigra/work/vigra-1-10-0/doc
$ ls $(vigra-config --docdir)
ls: /opt/local/var/macports/build/_Users_rschmidt_macports_dports_graphics_vigra/vigra/work/vigra-1-10-0/doc: No such file or directory

Okay, this error must have been there for some (longer) time already.

The reason for this is that the vigra-config script is generated during CMake's configure step. Inside the config/vigra-config.in file @DOCDIR@ is the variable, which will be replaced by CMake with the wrong directory.

However, this misbehaviour can be patched quite easy, as you may see in the Portfile.diff, which I appended to this topic.

Sorry, I forgot about this ticket somehow. Committed in r136469 with these changes:

• changed the patch block to a post-patch block, to make it easier if you need to add patchfiles in the future
• removed the comment since it is self-explanitory
• increased the revision since this changes the files that get installed

You should report this problem to the developers of vigra so that they can fix it properly in their build system. This does not seem like a MacPorts-specific problem.
