I just dealt with this... it turns out to be a bad combination of 
rubygems, rake, builder and rails. To fix, upgrade rake to 0.4.9.

Basically, gems can auto-require dependencies, meaning rake (prior to 
0.4.9, which disables auto-require) is required when running rails. 
Now, this doesn't normally cause a problem, except in builder, which 
uses a stripped down object to work its magic. When rake is required, 
it includes methods at the top-level, and this happens _after_ the 
builder object is stripped down. One of the methods that happens to be 
included by rake is link (as in symlink), which is then called instead 
of method_missing on the builder object. Thus the weird error message.

HTH,
