Hi
I have now tested building R10B-10 the same way as You did, and
I get a different error.

make fails with

( cd /usr/local/src/otp/otp_src_R10B-10/erts/start_scripts/tmp && \
        erlc -W   -I/usr/local/src/otp/otp_src_R10B-10/lib/kernel/ebin
-I/usr/local/src/otp/otp_src_R10B-10/lib/stdlib/ebin
-I/usr/local/src/otp/otp_src_R10B-10/lib/sasl/ebin -o
/usr/local/src/otp/otp_src_R10B-10/erts/start_scripts/start_clean.script
/usr/local/src/otp/otp_src_R10B-10/erts/start_scripts/start_clean.rel
)
stdlib: No valid version ("1.13.12") of .app file found. Found file
"/usr/local/lib/erlang/lib/stdlib-1.15.2/ebin/stdlib.app" with version
"1.15.2"

which shows that it only finds the stdlib from my R12B-2 installation.

Checking one of the newly compiled beam files in the R10B-10 tree
shows that it is compiled with the compiler from R12B-2. So it seems
like it is not possible to build, (at least R10B-10), when there is a newer
version also installed.

So try removing the ubuntu installed version of erlang and try builing again.
