 ** WARNING **

Your system does not have the wget executable - this is required if you
intend to build your own go-database. If you do intend to query a
pre-built database, you may continue safely.

wget comes as standard on most linux distributions. You should be able
to find a copy for more unixes. If you use OS X, wget is available via
fink

WARNING: ** You do not have XML::LibXSLT installed **

This is required if you intend to build your own go-database. If you

 ** WARNING **

You do not have the environment variable GO_ROOT set. This is required
for building the database, so that the system known where the XSL
files live.

You should set this to wherever your go-dev distribution lives; eg

  setenv GO_ROOT $HOME/go-dev/

This is required for some of the tests in the test suite, and for
building the GO Database. If you intend to use a pre-built database,
you can ignore these errors.
