According to the source gmt does not follow the file hierarchy standard. Thus the maintainer made some packaging choices (and hacks :)) and one of these choices was to keep all the executables in /usr/lib/gmt/bin except for GMT. GMT must be used as an interface to the other tools (using "GMT toolname" syntax).
