[erlang-questions] [Newbie] Failed/Skipped Erlang tests question...

[Plug Gulp]

Hi,

I am new to Erlang. I am running Ubuntu 15.04 on my laptop at home and
connect to wifi using dhcp. I built Erlang from Git repo using the
following command:

./otp_build setup -a --prefix=$HOME/Erlang/install
--with-libatomic_ops=$HOME/Erlang/libatomic_ops

Then I built the testsuite using:

./otp_build tests $HOME/Erlang/tests

And then ran the tests using following command:

$ERL_TOP/bin/erl -s ts install -s ts smoke_test batch -s init stop

I get some test failures and some tests are skipped. How do I make
these tests pass or are the results expected? The failed and skipped
test logs are as follows:
