# Prerequisite:
# * a decent checkout of LyX sources (probably you have it already)
# * Qt - build with shared or static libraries for the used platforms (default: i386 and ppc)
#   or - an unpacked source tree of Qt in $QTSOURCEDIR or in the sibling directory (variable QtSourceVersion)
# * for aspell support:
#   the aspell sources placed in a sibling directory (variable ASpellSource)
# * for hunspell support:
#   the hunspell sources placed in a sibling directory (variable HunSpellSource)
# * for dictionary deployment (only hunspell dicts and mythes thesauri are deployed per default):
#   - aspell:   the dictionary files of macports (in /opt/local/share/aspell and /opt/local/lib/aspell-0.60)
#   - hunspell: the dictionary files in the sibling directory dictionaries/dicts
#   - mythes:   the data and idx files in the sibling directory dictionaries/thes
# * for magic file type detection support:
#   the libmagic sources placed in a sibling directory (variable LibMagicSource)
