i've installed the jpeg-6b library but as i go to configure gd it cannot find jpeg? any ideas?

hecking freetype/freetype.h usability... yes
checking freetype/freetype.h presence... yes
checking for freetype/freetype.h... yes
checking whether it's freetype 2... yes
checking for jpeg_set_defaults in -ljpeg... no
checking for XpmReadFileToXpmImage in -lXpm... no

** Configuration summary for gd 2.0.15:

Support for PNG library: yes
Support for JPEG library: no
Support for Freetype 2.x library: yes
Support for Xpm library: no

configure: creating ./config.status
config.status: creating Makefile
config.status: creating config/Makefile
config.status: creating config/gdlib-config

install the jpeg-dev package for your distro

For my debian it finally worked with
apt-get install libjpeg62-dev
