Building in parallel using "make -j 2" causes an error while making inkpot:

At this point you can repeat the "make -j 2" command and it completes the build.

This is a bug in the brewer color data, as far as I can tell. Anyway, its not related to the problem with "make -j2"

I think what is happening is that the inkpot make is running ahead of the rbrtee make. I've made a couple of changes to prevent this, I hope. We'll see with the next snapshot build.

[north] This inkpot feature could have been phased in more carefully.

However, in general make -j tends to fail on a high performance machine (e.g. 4 CPU Mac Pro).

[ellson] Its strange because I don't get these failures on other multi-core machines with make -j. Perhaps Macs are just that much faster.

There are other cross-library dependencies in the code that have the potential for the same problem. I'm not convinced that the automake DEPENDENCIES feature that I just tried actually works, unless the dependency is in a subdirectory.

I also rearranged the build order such that this specific problem should have gone away in the nightly builds but I still need a more rigorous solution...

Note that this problem only affects package builders, not users of binary packages. If "make -j" doesn't work for package builds, then the immediate solution is to not use it. It not like its important when running a build from a cron job in the middle of the night.
