[erlang-questions] Erlang Different Versions

[Dmitry Kolesnikov]

I am using symbolic links

lrwxr-xr-x   1 root  wheel    11B Nov 23 23:11 otp -> otp_R15B02/
drwxr-xr-x   4 root  wheel   136B Nov 23 23:10 otp_R15B02
drwxr-xr-x   4 root  wheel   136B May 15 21:43 otp_R15B
drwxr-xr-x   4 root  wheel   136B Apr 10 19:25 otp_R14B02

otp is manually configured, complied and installed
