exif library not found

Hello Picfolio users.

I would need your help to make picfolio to make use of the exif data in 
my photos.

I have installed libexif, but running the configure.pl returns that exif 
is not supported. I don't understand much about Linux, but heres what I 
have tried. I have copied all libexif -files to /lib, /usr/lib, 
/usr/local/lib, with no help. I have compiled libexif-0.5.12 from 
source. I have edited configure.pl, more exactly the line
'$clo{'libdir'}  ||= "$clo{prefix}/lib";'
to try to find libraries from /lib, /usr/lib, /usr/local/lib, but with 
no help. I deleted '$clo{prefix}' when I tried other paths.

As none of these goofy tricks have helped me I though that some of you 
might know some real tricks.

I have Mandrake 9.2, Perl 5.8.1 and gcc 3.3.1.
Imlib2 is not either found by configure.pl, but it is installed.

Regards
 Samuli
