Have you installed the correct libraries and headers for jpeg, png and 
tiff? If not then imagemagick won't be able to link to these libraries. 
Try this:

- run synaptic
- look for libraries (starting lib...) containing 'jpeg', 'tif', and 
'png'. These are probably just libjpeg, libtiff, and libpng, but may be 
slightly differently named.
- now install the library (if it's not installed) /plus/ the development 
header files. These have the same name as the library with -dev or 
-devel at the end.
- try again with the ./configure; make ; make install process.
