foswiki fails to install

[Doug Sampson]

I'm trying to install a fresh instance of www/foswiki version 2.1.3 and it's failing as follows:

root at draco:/usr/ports/www/foswiki # make install clean
===>  Patching for foswiki-2.1.3
===>  Applying FreeBSD patches for foswiki-2.1.3
File to patch:
No file found--skip this patch? [n] y
1 out of 1 hunks ignored--saving rejects to Oops.rej
=> FreeBSD patch patch-minifycss failed to apply cleanly.
*** Error code 1

Stop.
make[1]: stopped in /usr/ports/www/foswiki
*** Error code 1

Stop.
make: stopped in /usr/ports/www/foswiki
root at draco:/usr/ports/www/foswiki #

What's up? Why would I need to apply patch(es) when installing for the first time?
