This appears to originate in line 79 of gr-qtui/src/lib/Makefile.am.
There is a variable $(QT_MOC_EXEC) which is null when QT is not
installed on the machine.  I not sure this line should even be
executed in this scenario, however, so it seems the real issue is
deeper.

This particular Makefile.am has been fragile in this area in the past;
it's another consequence of the requirement for QT apps to use a
pre-compiler to process header files.  We may be better off putting
the generated files under version control.

Fortunately, 'make distcheck' is intended for maintainers and hackers
on GNU Radio itself, and not really an issue for end users that are
only compiling and installing so they can write their own code on top
of the GNU Radio API.  So, as Michael said, it's probably not a
release issue.  If Tom can straighten it out, great.  But it's a risky
area of change that should get all its corner cases verified before
merging.
