It configures and builds fine here, but I have dev-libs/libpcre installed
already, which provides libpcrecpp. That looks to me like dev-libs/libpcre
needs to be added as a dependency in the ebuild.

Dep to libprcre added, it should be fixed now.

If you see this error with pcre installed, the headers may be corrupted, maybe
due to some related update.

Try emerge --oneshot libpcre - worked at least for me.

The error as shown in the configure.log:
