[nycbug-talk] creating "local" ports (fwd)

Hallo Charles Sprickman,

I like to point out a very easy way:

$ mkdir /usr/ports/LOCAL
$ echo "PKGCATEGORY?=LOCAL" > /usr/ports/LOCAL/makefile.inc
$ echo "PKGNAMESUFFIX?=-local" >> /usr/ports/LOCAL/makefile.inc

Copy a port you like to change into this.
build and install it from there.
You need _no_ modifications on a port.

PKGNAMESUFFIX or PKGNAMEPREFIX can be set to make standard and
local packages coexists.

If the master ports gets updated, you habe to merge the changes.

Or you create a slave-port., which referes to the master ports in the
normal ports tree.

All base tools support this.

a)
You can still add your own patches in /usr/ports/category/portname/files/

b)
You can create in  /usr/ports/category/portname/ a Makefile.local
that defines additional steps, dependencies ...

The minium requierement is:
/usr/ports/LOCAL/makefile.inc:PKGCATEGORY=LOCAL

My pkg_update tool supports this.
For each hostname there is an optional sed_file.

$ head /usr/ports/local/update/data/depends.*
