[plt-scheme] Still having trouble getting Tex2Page working...

OK, I ran it in DrScheme and got the same error.  I followed your -lc
suggestion, and then got a backtrace version:
c:\program files\plt\collects\tex2page\tex2page-aux.ss::239765:
file-exists?: expects argument of type <path or string>; given #f

So, the source of the error seems to be in the function
tex2page-file-if-exists, which is called from this line:

          (tex2page-file-if-exists (file-in-home ".tex2page.t2p"))

The problem is that file-in-home assumes that a HOME environment
variable is set.  If none is set, then it returns false, and that
causes tex2page-file-if-exists to mysteriously crash.

So, I set a HOME variable, and now it works.

A troublesome bug, but I'm glad you were able to help me identify it.
Hopefully it will be fixed in the future so others don't end up as
baffled as I was.

Thanks,

Mark
