Use the sysutils/portconf port and define the apporiate variable in
PREFIX/etc/ports.conf.

To create a patch you first need to create a backup of the original
file, then create the diff.

cp file.c file.c-orig
<make changes to file.c
diff -u file.c-orig file.c > patch-file.c

Then place the patch file into /usr/ports/<category>/<portname>/files.
