LJ::UserSearch looking for LJ/UserSearch.pm

[didactic_cudgel]

When running the search-lookup worker in workers.conf, I encountered an error: "Can't locate LJ/UserSearch.pm in @INC (@INC contains: /home/dw/cgi-bin /home/dw/src/s2 /cgi-bin /etc/perl /usr/local/lib/perl/5.10.1 /usr/local/share/perl/5.10.1 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.10 /usr/share/perl/5.10 /usr/local/lib/site_perl .) at bin/worker/search-lookup line 22.
BEGIN failed--compilation aborted at bin/worker/search-lookup line 22."

Line 22 of search-lookup is

"use LJ::UserSearch;"

There is a *folder* called LJ/UserSearch and it contains MetaUpdater.pm.
