msgfmt found in path, but $MSGFMT empty

[John Faith]

Hello,
I am trying to configure Inkscape on OS X 10.3.9 with autoconf 2.61
from MacPorts.  In config.log, I see:
 INTLTOOL_MSGFMT='/opt/local/bin/msgfmt'

, but later:
 MSGFMT=''

, which causes the build to fail since the Makefile tries to call the
empty $(MSGFMT).

I've seen 2 solutions to this problem, one was to set msgfmt path in
the generated Makefile, the other to set $MSGFMT and $GMSGFMT
environment variables.  Neither workaround seems quite right.

In configure.ac, is it correct that 'AC_PROG_INTLTOOL(0.22)' is
responsible for finding intltoolize, msgfmt, etc. and setting the
paths to the executables?  Any ideas on how to approach this undefined
variable, or just try 'echo' in configure?

Thanks!
,
John
