You could also use eix ... though I needed quite a time to figure it out ;)
# PRINT_SLOTS="false" eix -e -I sys-devel/automake --pure-packages
- --format "<installedversionsshort>"
1.9.6-r2 1.10.1-r1
Note however, that if you a package has multiple installed versions,
they are seperated by space. One could use
# PRINT_SLOTS="false" eix -e -I sys-devel/automake --pure-packages
- --format "<installedversionsshort:\n>"
But this prints an additional empty line at the beginning.
