The ebuilds for =net-mail/tpop3d-1.5.3 and =net-mail/tpop3d-1.5.3-r1 contain code which checks for variables like ENABLE_PASSWD, ENABLE_FLATFILE, BE_NICE, and so on. Shouldn’t these be replaced by (local) use flags? net-mail/cyrus-imapd already has a “drac” use flag. Perhaps the “offensive” use flag is a good replacement for BE_NICE (negated, of course). The ebuilds for tpop3d contain the line > # Make sure you also set $ENABLE_PASSWD , but the ebuilds should rather handle that automatically.
I committed tpop3d-1.5.4, which should fix all of these issues. Thanks for your report.
