The following may prove to be even faster as it fills the shell argument  
list as full as possible for each execution of grep.

% find /usr/ports -depth 3 -name pkg-plist -exec grep libfoobar.so \{} +

(notice the + at the end)

It's something I picked up from here: http://www.etalabs.net/sh_tricks.html
