Comment (by Joel.Brogniart@…):

 Sorry, I forgot to do some adaptation after my paste.

 Using informations from ticket:46570 I tried to modify port x11/auto-
 multiple-choice to user perl variants. I added the lines:


 {{{
 PortGroup               perl5 1.0
 ...
 perl5.require_variant   yes
 perl5.conflict_variants yes
 perl5.branches          5.16 5.18 5.20
 perl5.create_variants   ${perl5.branches}

 }}}

 and changed all "{{(port:p5.16}}}" to "{{{port:p${perl5.major}"}}}

 All my tests where done after having "{{{sudo port uninstall installed}}}"
 before .

 If I do

 {{{
 sudo port install auto-multiple-choice
 auto-multiple-choice
 }}}

 All works fine, the application is built, installed and works.

 If I do

 {{{
 sudo port install perl5
 sudo port install auto-multiple-choice
 auto-multiple-choice
 }}}

 All works fine too, the application is built, installed and works.

 But if I do

 {{{
 sudo port install perl5 +perl5_20
 sudo port install auto-multiple-choice
 auto-multiple-choice
 }}}
 The application is built, installed but when launched I get the error:

 {{{
 Can't locate AMC/Basic.pm in @INC (you may need to install the AMC::Basic
 module) (@INC contains: /opt/local/lib/perl5/site_perl/5.20/darwin-thread-
 multi-2level /opt/local/lib/perl5/site_perl/5.20
 /opt/local/lib/perl5/vendor_perl/5.20/darwin-thread-multi-2level
 /opt/local/lib/perl5/vendor_perl/5.20 /opt/local/lib/perl5/5.20/darwin-
 thread-multi-2level /opt/local/lib/perl5/5.20 .) at
 /opt/local/lib/AMC/perl/AMC-gui.pl line 45.
 BEGIN failed--compilation aborted at /opt/local/lib/AMC/perl/AMC-gui.pl
 line 45.
 }}}

 I get the same error when I install perl5_18. All auto-multiple-choice
 files stays at the same places, whatever perl variant is installed. The
 unreachable file is in
 "{{{/opt/local/lib/perl5/vendor_perl/AMC/Basic.pm}}}". With the default
 perl5 install (perl5_16), it seems that {{{@INC}}} contains the path
 "{{{/opt/local/lib/perl5/vendor_perl}}}" but not with perl5_18 and
 perl5_20.

 Are there other informations I should have added for the application to
 work with perl5_18 or perl5_20 variants?
