Hello, all. As some of you already know, the -jN option in make  
specifies the number of jobs (N) to run simultaneously. Fink CVS HEAD  
now provides support for this as follows:

* There's a new entry in fink.conf, MaxBuildJobs, which should contain  
the aforementioned N value. fink configure has been modified to  
include the corresponding prompt.

* There's a new boolean package description field: UseMaxBuildJobs. If  
true, Fink will automatically append -jN to MAKEFLAGS, even if  
NoSetMAKEFLAGS is true. The default is UseMaxBuildJobs: false.

This is an opt-in feature -- package maintainers must explicitly set  
UseMaxBuildJobs: true in their package descriptions. As there are some  
packages known not to build correctly with -j, this new feature won't  
affect them. If your package already sets -j, possibly via sysctl  
hw.ncpu or sysctl hw.activecpu, consider changing it UseMaxBuildJobs.  
Also, as Alex Strange insightfully observed, in general hw.activecpu  
should be used instead of hw.ncpu because users may choose to disable  
one or more CPUs/cores; fink configure uses hw.activecpu when  
suggesting an initial value for MaxBuildJobs.

If you're willing to checkout CVS HEAD, please test this new feature.  
Feedback is more than welcome.


Cheers,
