Please describe the problem:
I'm trying to update/test out Gnome-2.19.3 and things were compiling
along great until it got to gnome-panel-2.19.3.  Here's the error:

Gnome-2.19.2 didn't have this problem, and I just re-tried it to make sure it could get past this issue, and it completes without issue.  So it must be something that has changed in this package, or some unknown dependency.

Steps to reproduce:
1. Compile all requirements of gnome-panel up to this point
2. ./configure --prefix=/opt/gnome-2.19.3 --sysconfdir=/opt/gnome-2.19.3/etc --libexecdir=/opt/gnome-2.19.3/lib/gnom
e-panel --localstatedir=/opt/gnome-2.19.3/var/lib

3. make


Actual results:
Does not compile the clock applet

Expected results:
Should completely make like Gnome-2.19.2 does

Does this happen every time?
Yes
