UNZIP the generic l2h into $HOME.
Put jpeg-6b.zip and netpbm-10.18.18.zip in $HOME.
Then in a terminal:

Note: Please replace /home/facstaff/dommelen below with whatever the command
   echo $HOME
produces.

NOTE: djpeg, cjpeg, jpegtran, jpegtopnm and pnmtojpeg in deb6-32 and
deb6-64 are based on jpeg-9 and netpbm 10.47.45.  The rest, including
ppmtojpeg (a rename of pnmtojpeg), are based in jpeg-6b and netpbm
10.18.18.

NOTE: For jpeg-9, unlike jpeg-6b, libjpeg.a is in the .libs subfolder.

NOTE: To compile static versions of djpeg, cjpeg, and jpegtran using
jpeg-9 use './configure --disable-shared'. To make them truly static
(no system libraries either), use './configure --disable-shared
LDFLAGS=--static'

NOTE: To get truly statically linked netpbm programs, (no system
libraries either), need to go into Makefiles and add --static to the
relevant compile commands.
