Is that "install-exec-hook" target essential? Is there any typo in this make target? Thanks.
It's used to build the OSX appbundle, however it seems that automake isn't clever enough to notice that it's inside a conditional. I've committed a fix to ensure the target always exists, even if it doesn't do anything.
Please note that I'm right in the middle of re-hashing the whole build system, and we're looking at restructuring a lot of the source, so expect more failures in the future whilst things get straightened out!!
