hello,
I would like support for Perl debugger:
% perl -D -e ''
Recompile perl with -DDEBUGGING to use -D switch
I tried to add "debug" in my USE but it has no effect.
The only way I found is to add "-g" in my CFLAGS. But I don't want this flag for other programs.
% grep '^debug' /usr/portage/profiles/use.desc
debug - Tells configure and the makefiles to build for debugging. Effects vary across packages, but generally it will at least add -g to CFLAGS. Remember to set FEATURES=nostrip too
Why this use flag doesn't work?
Reproducible: Always
Steps to Reproduce:
1. USE="debug" emerge dev-lang/perl
2. Perl -D -e ''
Actual Results:
Recompile perl with -DDEBUGGING to use -D switch
Expected Results:

Added to perl and libperl, all ebuilds, using the CFLAGS=-g - simply using
-DDEBUGGING resulted in a perl that had debugging in -V output, but that didn't
actually do debugging (go figure)
