Wayland uses grep -P in a configure check for graphviz if asked to build documentation: checking for compatible dot version... /bin/grep: support for the -P option is not compiled into this --disable-perl-regexp binary no configure: error: Graphviz dot too old. Graphviz 2.26+ required for documentation build. Install required graphviz version or disable the documentation using --disable-documentation "dot -V" confirms I have graphviz 2.36. It builds with USE=-doc. It'd presumably also build with grep[pcre]. Easy fix would be to add doc? ( sys-apps/grep[pcre] ) to the dependencies. More involved fix would be to rewrite the problematic line in configure.ac (dot_version=`$DOT -V 2>&1|$GREP -oP '(?<=version\W)@<:@0-9.@:>@*(?=\W(.*))'`) to not require grep -P.

Looks like a rather complicated regex to rewrite. I've opted to add grep[pcre] to depend (as well as some other missing dependencies). Thanks for the report!
