Building gtk+

[Philip Peake <philip vogon net>]

I am having trouble building gtk+.

On Redhat 7.3, everything configures ok, and builds up to the point
of gtk-demo, where I get the following error:

creating gtk-demo
make[3]: Leaving directory `/home/philip/src/gtk+-2.0.8/demos/gtk-demo'
make[3]: Entering directory `/home/philip/src/gtk+-2.0.8/demos'

make[1]: *** [all-recursive] Error 1

make: *** [all-recursive-am] Error 2

I have to say that the error message is less than informative.
What exactly needs to be re-built ?

Any pointers welcome ...

BTW: I am not building this for any other reason than pan requiring this
library - and of course, this required other libraries ... so as I come back
up the stack, this is the last thing left before I can try (again) to
build pan.
