scrollkeeper installation: tons of XML errors

[Lev Serebryakov]

Hello, ports! How are you?

  I don't open PR, because it can be my local problem.

  When `textproc/scrollkeeper' (version 0.3.15_1,1) is being installed
many XML parser errors occurred (unknown entities) and parser try to
download DTD from www.oasis-open.org (I/O errors are only result). Of
course, I have all docbook DTDs installed via ports (latest versions)
on this box!

  Is it my local problem or bug in port installation procedure?

  FreeBSD 4.9-RELEASE, ports collection after gettext changes.
