MANUAL_FETCH

[Ernst de Haan]

I recognize an issue with manual distfile fetching and I would like your 
opinion.

Currently, there are quite a number of ports that require manual fetching, 
usually because of license restrictions. There seem to be 17 in the 'java' 
category alone:

$ grep 'manually fetch' ports/java/*/Makefile | wc -l
      17

Issues:
1. All these ports have a custom solution to this, and they all display 
different although similar messages to the user. Most seem to (ab)use the 
IGNORE variable for this;
2. The automatic building process cannot easily determine that a manual 
fetch is required.

Suggestion:
- Introduce generic support in bsd.port.mk that will allow ports to use one 
(or at least few) variables to indicate a manual fetch is required.

I'm not a Makefile-guru, but I could imagine something like this:

MANUAL_FETCH=	YES

instead of something like this:

.if !exists(${DISTDIR}/${DISTNAME}${EXTRACT_SUFX})
IGNORE= "You must manually fetch the distribution from ${DOWNLOAD_URL} and 
place it in ${DISTDIR} then run make a
gain"
.endif

Suggested patches are welcome, ofcourse! :-)
