You don't need this package for general hyperlinks. For an example hyperref setup, have a look at the preamble of the EmbeddedObjects manual.
If an URL contains an anchor # then something inside LyX breaks when using hyperref!
The upcoming new UserGuide (for LyX 1.5.2) contains this information in the URL section. regards Uwe
