Set the environment variable PIG_CLASSPATH=/opt/hadoop/conf.

I am running Mac OSX 10.6.7, Hadoop Core 0.20.2, and Pig 0.8.0.
Hadoop and
Pig are installed under /opt/hadoop and /opt/pig, respectively.
Hadoop is
set up to run in single-node pseudo-distributed mode. The
/opt/hadoop/conf/core-site.xml file looks like this:
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>fs.default.name</name>
<value>hdfs://localhost:9000</value>
</property>
</configuration>
I am able to run Hadoop jobs in this mode.
I am able to run pig in local mode with "pig -x local", but when I
try to
run just "pig" at the command line I get the following error.

The log file contains the same error message along with a trace

ends in HExecutionEngine.init(HExecutionEngine.java:168).
My classpath is set like so:
CLASSPATH=:/opt/hadoop/conf
What am I doing wrong?
Thanks.
