Since none of us know how your packages are installed (or if they are packages)...
To see what path is being found first, try:
Using the "locate" command can be helpful, especially if you search for "bin/erlc" instead of just erl. On a Debian system, for example, I see:
ceverett@REDACTED:~$ locate bin/erlc
Looking a bit closer:
ceverett@REDACTED:~$ which erlc
And looking even closer:
ceverett@REDACTED:~$ ls -l $(which erlc)
lrwxrwxrwx 1 root root 22 4月 2 19:23 /usr/bin/erlc -> ../lib/erlang/bin/erlc
Hopefully this gives you a place to start.
On a Fedora derivative You may want to use the alternatives command to simplify management of this sort of thing:
