Help with libjpeg

I am having serious problems trying to compile libjpeg,
which I need  
for JPEG support in the Python Imaging Library. After
bumping into  
several walls  realized that I need to configure the libjpeg
 
compilation with the enable-shared flag, as follows:
./configure --enable-shared

However, this results in an error:

checking host system type... Invalid configuration
`x86_64-unknown- 
linux-gnu': machine `x86_64-unknown' not recognized

...which does not allow the compilation to work. I've
looked into the  
error but all of the solutions seem to be package specific
and have  
nothing to do with libjpeg.

The worst thing is that libjpeg is, in fact, installed in
the system.  
For some reason the libjpeg.so.62 file in /usr/lib cannot be
read by  
setup.py.

Has anyone encountered this error? It's mission critical
that I  get  
PIL properly installed on this machine. Any help is greatly
appreciated!

Thanks,

Dan

You probably need to install some kind of jpeg-devel package
in order
to get the header file so that you can use the system
libjpeg.

PIL's build process needs the header files too.

have you looked for python-imaging packages for your
platform?  or at 
least jpeg-devel (or libjpeg-devel) packages?
