The warnings are genuine but innocuous-- there are some inconsisent
entries in the gaff database.

This is a genuine problem. Through an oversight, the tests for fastbld and
related components of sleap were not included in the automatic test suite, and
no one noticed that they were broken. We'll post a bug-fix when we figure
this out. In the meantime, try either going back to AmberTools 1.2, or running
the steps by hand with antechamber.

Thanks for the report....dac
