I tried to compile ERLANG V4.9.1 on a Red Hat 6.2 i386 machine which seemed to be successfull. However if I try to start ERLANG with its toolbar (erl -s toolbar) the shell gives me 

{'init terminating in do_boot',{startup_timeout,toolbar}}

after a while. I followed the installation instructions, doing: 

./configure prefix=/opt/ERLANG
make
make install

In addition I'd like to add that exactly the same problem arises if I use the RPMs provided by Red Hat's Powertools (erlang-47.4.1-10.i386.rpm, erlang-devel-47.4.1-10.i386.rpm, erlang-docs-47.4.1-10.i386.rpm, erlang-gs_apps-47.4.1-10.i386.rpm, erlang-gs_apps-devel-47.4.1-10.i386.rpm,  erlang-otp_libs-47.4.1-10.i386.rpm, erlang-otp_libs-devel-47.4.1-10.i386.rpm). 

I welcome any advices ...

Kind regards,
Alea Miras
