Problems found locating distfiles:
Package colorls: missing distfile ls.tar.gz
Package molden: missing distfile molden-4.6/molden4.6.tar.gz
Package softmaker-office-demo: missing distfile ofl06trial.tgz
Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden). All existing
SHA1 digests retained for now as an audit trail.
- obey CFLAGS, use $(CC) instead of cc in Makefile
- install data files in PREFIX/libdata/brs instead of PREFIX/lib,
rewrite whole "install" target
- correct paths in the manpage
- fix a warning (could be error with some compilers?) in #endif
