Hugin App bundles not finding binaries

[rpspringuel (Fr. Samuel Springuel)]

On Mac OS 10.10.5, hugin-app creates app bundles in the MacPorts folder. The command-line tools, naturally, are in /opt/local/bin. However, when launching processes using the GUI apps, the program looks for the command line tools in the same location as the GUI apps by default. Now, while I've been able to correct this via the preferences inside hugin for enblend and enfuse, I can't seem to correct this for nona and exiftool.

I've been able to bypass the problem for nona by creating a symlink from where the GUI is looking (/Applications/MacPorts/PTBatchGUI.app/Contents/MacOS/nona) to where nona actually is (/opt/local/bin/nona), but said solution is likely to be fragile and break when MacPorts updates hugin in the future.

Something similar seems to be occuring with exiftool, which is installed as /opt/local/bin/exiftool-5.22 (i.e. the PERL versionnumber is appended). However, in this case the log file isn't descriptive enough for me to tell where it's looking for exiftool so I don't know where to put the symlink to get around this (/usr/local/bin doesn't work).

When I reported this(​https://answers.launchpad.net/hugin/+question/294894) to the hugin developers, I got the following response:

In our CMake build system there are 2 possibilities to build on Mac:

1. A *nix way: Here the tools are installed and search in a fixed path, which is given during building. (For the external tools, like enblend, enfuse, exiftool, also the PATH environment variable is taken into account to search for the program.)
2. Building an OS/X bundle. In this case all the tools are bundled into a bundled and searched in the bundled.

Here it sounds there is something mixed up. I don't know what the MacPort maintainer do to build it (which patches are applied and with which options it is build). So please report your problems to the MacPort maintainers.
