Doesn't look relavent to me, Just looks like configure probing about
to find out how to deal with  the compiler. In a configure script it's
NORMAL for some tests to fail. You have to look for the error
configure itself gave and then work back from there.

The real error is here
 >configure:18421: checking for chemical_mime_data
 >configure:18428: $PKG_CONFIG --exists --print-errors 
"chemical-mime-data >= 0.1.94"

I know there is tension between manpower to get bugs filed and attention
paid to each bug but PLEASE if  you are going to file bugs for configure
errors learn to read config.log output and start from the end (just 
before the
variable dumps) not from the beginning.

Anyway getting back to the bug itself. The issue is that chemical-mime-data
lowered it's dependency on gnome-mime-data to a suggests. Normally in a
case like this I would cc the chemical-mime-data maintainers to ask for an
opinion on how best to fix this but it looks like they are the same 
people as
the gnome-chemistry-utils maintainers anyway.
