Hi, I found this today by accident - it seems that grep's ./configure doesn't work with so called minimal bash (enabled in bash's configure via --enable-minimal-config).
One can verify that not only by the failed ./configure process but also by content of config.log - there are several messages like: configure:3536: error: fn_grep: expected pattern Tested on the latest (3.3) version. If there are good reasons why ./configure needs full bash, I guess it shouldn't reference /bin/sh in that case. Cheers, Miro
