Not sure whether it is a libtool or perl or whatever bug, but snmp failed to build, because there are bashism "base_compile+=whatever" but is called with /bin/sh. Reproducible: Always Steps to Reproduce: 1. Symlink /bin/sh to dash 2. emerge -1v snmp Actual Results: >>> Compiling source in /var/tmp/portage/net-analyzer/net-snmp-5.4.2.1-r5/work/net-snmp-5.4.2.1 ... make -j1 -j1 WARNING: not running

The problem seems to be that libtool is configured from the current shell (bash) and hence it makes the assumption that it is safe to call with sh despite the shebang bash. However, with sh symlinked to dash (and root's shell being bash), the assumption is violated.
This _should_ be fixed as of 5.7.2_rc1 but please reopen if it's still an issue.
