You appear to be using the C-shell.  If this is the case, you have two
different sorts of variable available: shell variables and environment
variables.  There are several differences, but the relevant one here is
that shell variables are not passed to commands, whereas environment
variables are.  As you may guess at this point, you are setting a shell
variable called XAPPLRESDIR; you want to set an environment variable.
(Both sorts of variable are understood by the $ expansion mechanism in
the shell.)

Try instead

setenv XAPPLRESDIR `pwd`

(using $cwd instead of `pwd` would probably be faster.)  Note the lack
of an = sign; the syntax is somewhat inconsistent.

Bourne shells (and derivatives) have the same basic problem, but the
terminology is different: all variables are considered to be the same
sort of thing, but some are exported and some aren't.  But that's
irrelevant in your case; that set command would not have worked in sh.

This one can't really be answered with surety without more information.

I have two guesses, though.

One is that your X server is running on an X terminal, another
workstation, or some other machine which can't access the path you
gave.  (Your *clients* may be able to access the font directory, but
that has nothing to do with it.  The *server* has to be able to get at
it in order for it to work in the font path.)

The other is that you didn't run mkfontdir (or your server's analog) to
create the fonts.dir (or analog) in that directory.
