I can't tell why gconftool-2 is linked with libffi at all.

gconf: rebuild with latest libffi

This is probably fixing the symptom rather than the
actual cause but, as per the attached ticket, it's not clear
at all why gconftool-2 wants to link with libffi.

Closes #61226.

Well, after this attempt, the problem seems to be restricted to the 10.8 buildbot and coming from /opt/local/bin/orbit-idl-2 provided by orbit2.

If I had to guess, perhaps orbit2 was infected by an earlier version of glib2 via /opt/local/bin/glib-genmarshal. If that's the case then orbit2 has the old libffi reference baked in and needs a revbump to rebuild with the lastest version of glib2 which is built with libffi 3.3. All the other buildbot rebuilt gconf correctly and without reference to libffi.

As I say, this is a guess, so I'm open to any other interpretation of the data so far.

LUCKILY we only update things like libffi once or twice a decade...

orbit2: rebuild with latest glib2

Possibly gratuitous, but may contribute to fixing
broken libffi linking issues wrt gconf on ports-10.8_x86_64-builder.

Appears to not have been rebuilt since we first moved to GitHub.

See #61226

[dbevans (David B. Evans)]

After a successful rebuild of orbit2, gconf built without problems on ports-10.8_x86_64-builder.
