1. HP-UX's stock RCS is too old; you need to get a current v5.7 and fix the $rcs... variables accordingly
2. HP-UX's native diff does not support all options needed by TWiki; get GNU diff
3. Using perl extensions is troublesome, if compilers are mixed.

Main source for HP-UX packages:

• Software Porting And Archive Centre for HP-UX http://hpux.connect.org.uk/ -- HP focus, slow updates on "exotic" packages
• The Written Word http://www.thewrittenword.com/ -- multi platform focus, includes HP, faster updates, odd installer

See DiffInvalidOption for an HP-UX installation that needed a fresh copy of RCS and GNU diff to work properly.

See RCSDiffNotWorkingBetweenRevisions for issues with HP-UX RCS and diff, solved by compiling fresh versions.

Just wanted to let people know that twiki works on HP-UX 11i, running Apache 2.0 as well. We also had to rebuild rcs to point to the appropriate version of diff.
