Please copy the source archive for the Mozilla sources into this directory.
At the moment "seamonkey-1.1.14.source.tar.gz" is required, it can be found
here:
 ftp://ftp.mozilla.org/pub/mozilla.org/seamonkey/releases/1.1.14

If this version is not available anymore, try a later 1.1.x release - chances
are good it will work, too.

Windows builders need also
  "vc8-moztools.zip"
which can be found here:
  ftp://ftp.mozilla.org/pub/mozilla.org/mozilla/libraries/win32/historic/vc8/
