Even though the Bitbucket page says they support "UNIX", but I think they really mean just Linux. The
make script needs to run their included
bin/tnt program. Running
file bin/tnt shows:
tnt: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), statically linked, for GNU/Linux 2.0.0, stripped
For comparison, a "normal" Mac OS X UNIX command (like
man) returns this:
/usr/bin/man: Mach-O 64-bit executable x86_64
Conclusion: the bundled
tnt program is not Mac-compatible.
Workaround 1: Download/compile a Mac version of
tnt? Given what you're trying to accomlish, I'm guessing this is the TNT homepage: http://www.coli.uni-saarland.de/~thorsten/tnt/
But, they don't make it easy to get the source code, so I'm not sure how lucky you'll be trying that path.
Workaround 2: Get or borrow a Linux computer.
