Yup.  See:

Since 2.2, PyTables does not includes Numexpr anymore and depends on Numexpr
(>= 1.3.1) explicitly.  The reason is that, after "normal" Numexpr got all
the enhancements that PyTables needed (mainly support for booleans and
strided and unaligned data), it does not make sense to have different
Numexpr's anymore.
