Re: $(datadir)/.../dvips vs. .../ps

[Karl Berry]

    An alternative to the symlink is to set the environment variable
    TEXPSHEADERS to "/usr/local/share/lilypond/1.6.6/tex/:"

Actually, in order to find the postscript headers I think .../ps is
needed, not .../tex.

Anyway, neither one fixes xdvi for me.  I tried a number of
variations (.../ps//, .../ps, .../1.6.6//, etc.). I always get
  gs: Error: /undefined in set_tex_dimen
which I believe is a symptom of not reading music-drawing-routines.ps.

Trying xdvi -debug -1 shows that it is not reading the TEXPSHEADERS
environment variable at all.  Bizarre.

What finally worked for me was to do
export HOMETEXMF=/usr/local/gnu/share/lilypond/1.6.6

Now if only I could figure out how to get my mandolin tablature working
again :).

Thanks,
