I've had similar problems in the past.  It usually comes down to the
build requiring some package that happens to be present on your system
but not listed in the Build-Depends field, so dpkg-buildpackage works,
but sbuild doesn't.  One thing I've done (boring, but has worked in
this sort of case) is to search the code for any occurrences of
"import" (patterns such as r'^\s*import\s' and
r'^\s*from\s.*\simport\s' are useful here); it might reveal a package
not listed in the install requirements.

Best wishes,
