system is not happy with it. I just checked, and the tarball I
downloaded from sourceforge is identical to the one I used the last time
I updated squirrelmail.  You should end up with:

after deleting the file, I run make and get

# make
===>  Patching for squirrelmail-1.4.2_1
===>  Applying FreeBSD patches for squirrelmail-1.4.2_1
patch: **** can't cd to
/usr/ports/mail/squirrelmail/work/squirrelmail-1.4.2: No such file or
directory
>> Patch patch-config-config_default.php failed to apply cleanly.
*** Error code 1

Stop in /usr/ports/mail/squirrelmail.

what I can do to get the port downloaded again?  or how can I clean up
after a failed install?
