Thanks for reporting this. I've fixed it in Makefile::GraphViz 0.17
(as well as its dependency, Makefile::Parser 0.210) and they are
already on CPAN now. Also, I've added support for double colon rules
as a bonus ;) You can try gvmake again to see if it works ;)
Because the Makefile::Parser engine used by the gvmake script is
rather limited in functionalities, it's recommended to call the
makesimple script (provided by Makefile::Parser) to convert your
makefiles to the simplest form __before__ feeding it directly to
gvmake. Here's the commands that *I* normally use myself:
$ makesimple -f input.mk > simplest.mk
$ gvmake -a -f simplest.mk
It's worth mentioning that the makesimple script requires the "make"
program in PATH to be at least GNU make 3.81 (which can be downloaded
from ftp://ftp.gnu.org/pub/gnu/make/ . And it's also compiled well on
Win32 with the Visual C/C++ compiler BTW.

Heh, sorry about the twisty code...it also took me a while to make a patch :P
Thanks!
