It turned out not to be directly a shell issue (I tried with forcing shell to bash), but a BSD make vs GNU make.
using "gmake" did use the correct shell, and produced a detailed log, which is attached.

If I understand correctly, the failure is triggered in line 177 in the attached log.
running "grep -r '^'" was supposed to return zero, but it returns 2.

I disabled the removal of the temporary directory, and so was able to reproduce manually:

For comparison,
On Linux (Ubuntu 14.04.1 amd64), the exit code is zero, somehow c,d,e are ignored:
