Bug 211886 – mail-mta/ssmtp needless virtual/libc dependency

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Sebastian Redl 2008-02-29 12:42:26 UTC]

All mail-mta/ssmtp ebuilds explicitly list virtual/libc as a dependency. Because virtual/libc is part of the system package set, this is clearly unnecessary.

In addition, because the explicit dependency is followed by the dependency resolver, this means that an emerge -e world (for example, after a GCC upgrade) pulls in glibc and gcc, when the previous emerge -e system has already re-merged them, leading to a considerably increased merging time due to the redundant double merge of these big packages.

mail-mta/ssmtp should not depend on virtual/libc.
In addition, if such a thing doesn't exist, a QA rule should automatically point out packages that are not in the system set but depend on packages in the system set.

This would always happen with -e world; that's why tools like emwrap.sh [1] and 
and Guenther's upgrade script [2] were written.

Not sure about the dep on virtual/libc in itself; just that removing it would not solve the above issue.

I just committet ssmtp-2.62 which fixes this bug.
