|

|
| mv /usr/include /usr/include.hold; ln -s $(STAGING_DIR)/usr/include
| /usr/include
| cd /usr/ports/$(PORT_DIR); $(BMAKE) $(ARGS) install clean
| rm /usr/include; mv /usr/include.hold /usr/include
|
| this is *NOT* a clean solution :-)
If you want to change things on a port by port basis, you can:
1) use poudriere to build you a jail with a patch you provide, and build
ports with poudriere testport or poudriere bulk.
2) on each port's directory, you create a Makefile.local and put your
things in it.
3) in /etc/make.conf you use some kind of construct like:
.if ${.CURDIR:M*editors/vim}
FOO=bar
.endif
