[X2Go-User] trouble building nxlibs 3.5.0.21

[Short, Kermit]

Greetings,
   I'm trying to build nx-libs from a source tarball for version
3.5.0.21.  When I run:
make build-lite

I get a compilation abort while building nxcomp.  The compiler is
looking for jpeglib.h.  I've run a quick find and that file doesn't
exist in the hierarchy created by the tarball.

g++ -c -O3 -fno-rtti -fno-exceptions -I../nx-X11/exports/include
-Wmissing-declarations -fPIC -DIN_ADDR_T=in_addr_t -DVERSION=\"3.5.0\"
-DPACKAGE_NAME=\"\" -DPACKAGE_TARNAME=\"\" -DPACKAGE_VERSION=\"\"
-DPACKAGE_STRING=\"\" -DPACKAGE_BUGREPORT=\"\" -DPACKAGE_URL=\"\" -Wall
-Wpointer-arith   Jpeg.cpp
Jpeg.cpp:29:23: fatal error: jpeglib.h: No such file or directory
compilation terminated.
make[1]: *** [Jpeg.o] Error 1
make[1]: Leaving directory `/var/tmp/nx-libs-3.5.0.21/nxcomp'
make: *** [build-lite] Error 2  

This is probably mostly due to my reluctance (and inability in some
cases) to clone the git source tree, but I'm a bit old school when it
comes to building software...this automake stuff is about as modern as I
can get.

If anyone has any howtos on how to clone the nx-libs modules using http
transports (I'm behind a fairly thorough firewall and web proxy) I'm
willing to give it a shot, otherwise where can I obtain that header
file?

Thanks!
