[erlang-bugs] R14B02: "make install-docs" fails on Ubuntu 10.04 / 10.10 (using the source tar-ball)

[Lukas Larsson]

Hi Boris and Andrew!

Thanks for pointing this out. It has to do with the fact that an old
version of escript (and in extension the erlang VM) is used to build the
docs. A workaround for now is to add /your/r14b02/path/bin/ into your
PATH and then build the docs. 

I'm however unsure if the patch you provided will work for us as it
might not always be true that one would want to use the
$ERL_TOP/bin/escript emulator to build the docs. I'll try to come up
with a solutions which works for both scenarios.
