make search name/key broken with ports directory moved

[Adam Fabian]

Since I moved my ports directory, I *think*, make search name and
make search key don't do anything.  I stuck my ports directory under
/home since /usr was getting a bit tight.  I set PORTSDIR=/home/usr/ports
in make.conf, which is where my ports tree is.  Now, make search
name and make search key don't do anything.  No error messages, no
output whatsoever, exit code of 0.

Any help would be appreciated.
