Hello,<br>
<br>
Unfortunately I cannot reproduce your error. Could you try to insert
this into the beginning
/Users/barryh/otp_src_R15B01/lib/erl_docgen/priv/bin/xref_mod_app.escript
and report back with your findings?<br>

<div>Comments:</div>
<div>After some searching, it seems a similar issue has been
encountered before. In particular, there were some reports
following the release of R14B02 in March 2011, with commentary
confirming the behavior on Ubuntu, CentOS, and Mac OS X. Here
are links to the start of the related threads, one in
erlang-questions and the other in erlang-bugs:</div>

<div>I confirmed the presence of xmerl-X.X.X in the
installation's lib directory:</div>

<div>I also confirmed that the xmerl module could be loaded in
my shell using a small example from <a

but the behavior remained the same.</div>

<div>I also tried adding the source's bin directory to $PATH
instead of the installed system's bin directory, but the
