What do mean? Do you think that Sage should check that all packages are installed before starting? I don't think we should do that: imagine that for some reason R does not build on a particular system. That user might be happily using Sage without R installed. Also, Sage itself is used by certain pieces of the build system (conway_polynomials for example uses Sage to install a pickle).

Well, that's a different thing entirely. If no error message shows up, this is indeed a problem with the build scripts.

I had
reissued make and the build completed, including building
documentation!  Or so it said, anyway.  It never noticed the missing
packages.
I don't get it. You said you *interrupted* the build.

Bizarrely, doing "sudo make" so it could write to my local folder FIRST
rebuilt the documentation (quick because no changes) and THEN just now
started building cddlib, gfan, cvxopt, and a host of other stuff.  I
will repeat that there were no relevant error messages in the log files.
Yes, this order is optimized for parallel builds. With parallel builds, you want to start building the documentation as soon as possible since it takes a long time.
