Macport version of latex does not intall changebar
package referenced by sane.tex.
Commented out this reference since its not actually
used by any docs. This should allow generating
with a wider range of latex versions.
Also added quotes around TEXINPUTS (where to find
our custom distributed html.sty) since OSX often
has spaces in path names.
