I realized what happens.

Compiling the trunk, I saw that GIMP (also version >= 2.3.18)
needs "libexif >= 0.6.15", while there is no RPM repository
with libexif version bigger than 0.6.13. (Probably most RPM
based distros have the libexif outdated).

Observe that version libexif 0.6.15 has a delicate security bug
that was only fixed in the last version 0.6.16 (2007-06-12).

My fault, I should have checked better the config log. Sorry.

    Thanks again, Mukund.
