  Then the path lookup is wrong. If you run "CONFIG_SHELL=sh -x ; sh -x
configure" you can look in the output to see why it fails, or send it to
me and I'll look into it.

  Sigh, I wish Debian could be more up to date. Fltk1 and Fltk2 are pretty
different from each other, so you'd have to change the GUI code.

  Hum, we do look for Xft. I guess one of these days I should setup a
machine with Etch and see what's so different. Can you email me the
output of "ldd gnash" ?

  Probably. It would have to be done using the new $pathlist, so it
still works when cross configuring.

  And then try AC_CHECK_LIB and AC_CHECK_HEADER last.

  It's probably more efficient for me or Markus to fix these issues, but
learn autotools if you want. :-)
