mail/enigmail-thunderbird broken with the latest thunderbird update

[Doug Barton]

First let me say a big thank you to the gecko@ team. It's obvious that 
the latest round of updates includes an enormous amount of work, and 
both the thunderbird build and the firefox PGO build went flawlessly. 
I've been using the new firefox and it is great so far. :)

The problem comes in with the enigmail-thunderbird build. After 
re-building thunderbird and starting the enigmail build I get this:

cd 
/usr/local/tmp/WRKDIRPREFIX/frontier/ports-svn/head/mail/enigmail-thunderbird/work/comm-release/mailnews/extensions/enigmail 
&& /usr/bin/env SHELL=/bin/sh

../../../config/autoconf.mk: No such file or directory
gmake: *** No rule to make target `../../../config/autoconf.mk'.  Stop.
*** [do-build] Error code 2

I looked in that directory and the autoconf.mk.in file is there, but the 
.mk file has not been built. Given the complexity of the enigmail build 
process it isn't obvious to me what the solution is.

Sorry to be the bearer of bad news,
