[jdmarshall]

with I get a different but similar error:
export KERL_CONFIGURE_OPTIONS="--without-javac"

Alternately I can get beam signal 10 or error 1 in the same file. For the latter, even following these instructions and using latest only changes the error code to 1 from 139 but still failing in the same file.

Looks as if one of the environment variables left over from removing the old ErlangInstaller caused this error.

Cleaning up .bash_login and starting a new shell cleared the issue. Leaving for posterity.
