And here is a stab at that:
$ echo "This is perl, version 4.0" | sed -n 's/This is perl.*v[a-z
]*\([0-9]\.[\.0-9]*\).*$/\1/p'
4.0
$ echo "This is perl, v5.8.0" | sed -n 's/This is perl.*v[a-z
]*\([0-9]\.[\.0-9]*\).*$/\1/p'
5.8.0
$ echo "This is perl, v5.10.1" | sed -n 's/This is perl.*v[a-z
]*\([0-9]\.[\.0-9]*\).*$/\1/p'
5.10.1
$ echo "This is perl 5, version 11, subversion 4
(v5.11.4-114-ga4cc961*) built for" | sed -n 's/This is perl.*v[a-z
]*\([0-9]\.[\.0-9]*\).*$/\1/p'
5.11.4
