>Description:
While building mpg123-oss package, I get this error:
433     ===> Building binary package for mpg123-oss-1.12.5nb1
434     => Creating binary package /tmp/packages/All/mpg123-oss-1.12.5nb1.tgz
435     ===> Install binary package of mpg123-oss-1.12.5nb1
436     pkg_add: Conflicting PLIST with mpg123-1.12.5nb1: 
lib/mpg123/output_oss.la
437     pkg_add: 1 package addition failed

440     Stop.

The mpg123-oss PLIST is short:
lib/mpg123/output_oss.la

The mpg123 PLIST is longer, with this interesting entry:
${PLIST.oss}lib/mpg123/output_oss.la
>How-To-Repeat:

>Fix:
No idea.  Is this intentional or an oversight?
Why does mpg123-oss exist if the same library is available with mpg123.

Should the former be removed?
