Comment 0 for bug 992047

MacPorts recently upgraded automake to 1.12 [1]. Inkscape's 'autogen.sh' script doesn't detect this version. The script instead falls back to the system version (automake 1.10 - if present at all, no longer provided with Xcode >= 4.3.x on Lion and Mountain Lion AFAIK). The system version of automake however lacks several required macros (only present in MacPorts' version), and the script fails:

I am testing that you have the required versions of autoconf,
automake, glib-gettextize and intltoolize. This test is not foolproof and
if anything goes wrong, there may be guidance in the file HACKING.txt

checking for autoconf >= 2.52 ... yes (version 2.69)
checking for automake >= 1.10 ... yes (version 1.10)
checking for glib-gettextize >= 2.0.0 ... yes (version 2.32.1)
checking for intltool >= 0.17 ... yes (version 0.50.2)

Attached patch works around the issue similar to the earlier fix for automake 1.11 in revision 9109:
<http://bazaar.launchpad.net/~inkscape.dev/inkscape/trunk/revision/9109>

A better solution might be to modify/update 'autgen.sh' as proposed in the merge request to update the autotools (untested):

Revision 10658: "autogen.sh: Use autoreconf instead custom script"
