[erlang-questions] Keep multiple erlang releases in the same mechine

[Serge Aleynikov]

You can give the "--prefix=PATH" option to the configure script.  This 
will ensure that when you do "make install", Erlang will be installed in 
a location different from default.

As we switch between releases often, we usually do it such that releases 
go to:

/opt/erlang/R10B-9
/opt/erlang/R11B-1
/opt/erlang/R11B-2
...

and also create a link to the most recent release:

ln -s /opt/erlang/R11B-2 /opt/erlang/current

Then the programs such as /usr/local/bin/erl can be pointed to:

/opt/erlang/current/bin/erl

etc.

Whenever you need to switch between releases you repoint 
/opt/erlang/current to a different directory underneath /opt/erlang.

Perhaps others use different approaches but this one works well for us.

Regards,

Serge
