>Description:
Most emacs modules/packages have no common files when they are built
with EMACS_TYPE=xemacsXXX and EMACS_TYPE=emacsYY

But they are always marked as conflicting by default.

I think this mark should be removed and really conflicting packages
should be either marked as such individually or conflict should be
resolved homehow.

Full description of the problem with a proof of the above statement
is available here.

 The offending logic is still there (AFAICT)... however, it seems to me
 that this should be sorted out as part of a general rehab of emacs
 modules to support proper multiversion builds. Then one would be able
 to install the various versions reliably without making a mess.

 Does that seem reasonable?

 I guess the main fault line is between Emacsen and XEmacsen - the 
 various Emacsen are much more likely to store things in the same place. 
 Looking at emacs/modules.mk, the {x,}e* variables are clearly 
 distinguished, paths all different, and there is an xemacs prefix pre-set.

 Wouldn't it be enough to just remove the CONFLICTS settings, then deal 
 with the fallout from conflicting PLISTs as it happens?

 Cheerio,
 hauke

 Probably... go ahead :-)

 I think we ought to have proper multiversion builds for elisp packages
 anyway, for various reasons (one being that then the emacs and xemacs
 versions can both be build-tested by pkgbuild) but there's no reason
 that should prevent sorting out things that can be done without it.

 Module Name:	pkgsrc
 Committed By:	dholland
 Date:		Sat May 14 21:57:01 UTC 2022

 Modified Files:
 	pkgsrc/editors/emacs: modules.mk

 Log Message:
 editors/emacs/modules.mk: remove explicit CONFLICTS

 There's no need for CONFLICTS between the xemacs and emacs versions of
 the same elisp package unless the PLISTs overlap, and if they do (most
 don't because they install into different subtrees), that fact is
 sufficient.

 As suggested by PR 39886, a long long time ago.
