Number 3 below is fixed. Number 5 is a bootstrap problem, which
could be solved perhaps with

make bin; make install bin; make install modules packages

or by doing a real two stage build. But I agree that is a major
change in the build process.

This can also be hacked by doing a make install, wait until it breaks,
then do another make install. I am not suggesting this as an actual
solution.

It's not a problem if you have a version of R installed, at least not
if that R.bin has all the required symbols (but I think the R.bin from
1.6.2 misses one symbol needed by the 1.7.0 version of ctest,
for example). Again this does not provide a solution.

I'll see if the bundle_loader solution can be changed in any
way (for instance by using weak binding, so that the symbol
does not have to be there at link time, only at run time).
