Error when starting web_server

[SamuelCox]

Hi, I get the following trace when starting the web_server, any idea why this happens? As far as I can tell the install is correct, and I have the graphviz dependency.

{error,

Hi, I've figured out that the problem is this specific line: https://github.com/huiqing/percept2/blob/master/src/percept2.erl#L376

inets:start(httpd, Config) is failing, presumably due to the mod_include part of the config. Does the app need this module or can I comment this line out?

Hi again. For what it's worth, superficially my suggested fix has fixed it. Not sure if it will cause me to have problems down the line. I can send in a pull request or you can just do it yourself if you'd like, since its such a trivial change.
