ImageMagick requires the header files to validate a particular delegate
library-- which as discussed generally comes with the development package.
Under Fedora, for example, there is generally a library RPM and a companion
development RPM that includes the library headers.  For JPEG, ImageMagick
is looking for jpeg.h.  Without it, ImageMagick cannot properly map the
JPEG structure members to match the requirements of the installed JPEG
library.
