galeon2 build fails to find mozilla-gtkmozembed-gtk2

[Sheldon Hearn]

Hi folks,

I'm trying to build galeon2 on a 5.1-CURRENT (just prior to 5.2-BETA)
box, using an up-to-date ports tree.

I have mozilla-gtk2-1.5 and mozilla-headers-1.5_1 installed and am
building with WITH_MOZILLA=mozilla-gtk2.

I get this error:

checking for mozilla-gtkmozembed-gtk2... Package
	mozilla-gtkmozembed-gtk2 was not found in the pkg-config search path.
Perhaps you should add the directory containing `mozilla-gtkmozembed-gtk2.pc'
	to the PKG_CONFIG_PATH environment variable
No package 'mozilla-gtkmozembed-gtk2' found

configure: error: Library requirements (mozilla-gtkmozembed-gtk2) not
met; consider adjusting the PKG_CONFIG_PATH environment variable if your
libraries are in a nonstandard prefix so pkg-config can find them.

What am I missing?

Ciao,
Sheldon.
