I came across this while upgrading an RH51 box. I don't know if you need
these, but here it goes.. hope it's useful :)
imlib seems to require at least gtk+ 1.2.1 installed before it will rebuild
nicely. Autoconf will warn about this, but won't stop compiling, and all
files won't get done.
Incomplete/missing BuildPreReq's aren't normally considered a bug.
