archivers/rpm4: fix install manual pages, build without PYTHON, silent grab doxygen and dot from graphviz

[vvd]

Summary

1. Rebuilding manpages require textproc/hs-pandoc (depends on huge lang/ghc).

Bat package have all manpages prebuilded already. Add option MANPAGES for rebuild manual pages, if off - use prebuilded.

2. Stage error if PYTHON option is off.

3. Fix silent grab devel/doxygen and dot from graphics/graphviz.

archivers/rpm4/Makefile

%%MANPAGES%% prefix in missing in pkg-plist for manpages files

MANPAGES option is not active by default and has to be added here

If you remove the PANADOC test, manpages will be installed even if MANPAGES option is disabled

same here

My english is poor and maybe description isn't clear: option MANPAGES turn on rebuild manual pages. With MANPAGES off - installed included in tarball prebuilded manual pages.

archivers/rpm4/Makefile

63–69

Check description - MANPAGES for REBUILD manual pages, not for install already included in tarball.

64

Manual pages included in tarball installed by default same as was in 4.18.0.

PANADOC need for REBUILD manual pages only but not for install included in tarball.

Hi Vladimir,

I just committed a fix for rpm4 build with

• the patches you made for manpages install, removing panadoc dependency
• including the fixes for python build

but without the MANPAGES option I found unnecessary and quite confusing

I add you as reporter, since you did the heads-up and provide part of the fixes
Thanks for your help

Add please

ac_cv_path_DOXYGEN=no \
ac_cv_prog_HAVE_DOT=no \
ac_cv_path_PANDOC=no

to CONFIGURE_ARGS to prevent silent grab doxygen, graphviz or pandoc if installed.
