[erlang-questions] Erlyweb Problem

[Tony Perrie]

I'm attempting to run the Erlyweb example, but I'm getting the following error:

sudo yaws -i --conf yaws.conf

The database is accessible with the password, and the data is there.

I tried adding a "-pa /Users/jperrie/erlapps/music/src/components" to
the command-line as well.

I'm not really sure how to debug this though.   I feel like the
"musician" component isn't getting loaded, but I'm not sure how to
load it.

Any help would be appreciated,

Tony
