Here some further comments.

The break happens at 2.4.0. R 2.3.1 still compiles beautifully. It seems
that there are two issues:

1. The configure script at 2.4.0 introduces new tests, and regards
vecLib BLAS incomplete. The configure ignores the --with-blas switch and
decides to build new BLAS and LAPACK. Regarding MacOS X vecLib BLAS
incomplete may be fair, but it is unfortunate, since vecLib is optimized
for the architecture.

2. Building LAPACK fails and so does building R.

I attach diff of configure output.

What is intriguing that things are a bit different in another MacOS
10.3.9 G4 computer: there also BLAS is regarded as incomplete, but
building of BLAS and LAPACK succeeded. 

Here the diff (I put it here since the mailing group has been anal with
attachments):
