gobject-introspection broken again or something else wrong...?

[Michelle Sullivan]

Seems every week or two my build servers all fail and it's mostly one of
2 packages

devel/gobject-introspection
dns/bind99

Today its gobject-introspection:

checking for backtrace_symbols... no
checking whether /usr/local/bin/python2.7 version is >= 2.5... yes
checking for /usr/local/bin/python2.7 version... 2.7
checking for /usr/local/bin/python2.7 platform... freebsd9
checking for /usr/local/bin/python2.7 script directory...
${prefix}/lib/python2.7/site-packages
checking for /usr/local/bin/python2.7 extension module directory...
${exec_prefix}/lib/python2.7/site-packages
checking for headers required to compile python extensions... not found
configure: error: Python headers not found
===>  Script "configure" failed unexpectedly.
Please run the gnomelogalyzer, available from
"http://www.freebsd.org/gnome/gnomelogalyzer.sh", which will diagnose the
problem and suggest a solution. If - and only if - the gnomelogalyzer cannot
solve the problem, report the build failure to the FreeBSD GNOME team at
gnome at FreeBSD.org, and attach (a)
"/wrkdirs/usr/ports/devel/gobject-introspection/work/gobject-introspection-1.36.0/config.log",
(b) the output of the failed make command, and (c) the gnomelogalyzer
output.
Also, it might be a good idea to provide an overview of all packages
installed
on your system (i.e. an `ls /var/db/pkg`). Put your attachment up on any
website, copy-and-paste into http://freebsd-gnome.pastebin.com, or use
send-pr(1) with the attachment. Try to avoid sending any attachments to the
mailing list (gnome at FreeBSD.org), because attachments sent to FreeBSD
mailing
lists are usually discarded by the mailing list software.
*** [do-configure] Error code 1

Stop in /usr/ports/devel/gobject-introspection.
