how to remove a "bogus" package?

[Kostas Oikonomou]

I built /usr/ports/math/py-numpy with Python 3.2 on FreeBSD 10.0.  The
port was installed as package

[ko at wiley ~]$ pkg info py32-numpy
py32-numpy-1.8.0,1
Name           : py32-numpy
Version        : 1.8.0,1
Installed on   : Wed Feb 26 19:37:09 EST 2014
Origin         : math/py-numpy
Architecture   : freebsd:10:x86:64
Prefix         : /usr/local
Categories     : python math
Licenses       : BSD3CLAUSE
Maintainer     : python at FreeBSD.org
WWW            : http://www.numpy.org/
Comment        : The New Numeric Extension to Python
Options   

...

However, some "parts" of pkg seem to think that there is also py27-numpy
installed:

[ko at wiley ~]$ pkg info py27-numpy
pkg: No package(s) matching py27-numpy
[ko at wiley ~]$
[ko at wiley ~]$ pkg search py27-numpy
py27-numpy-1.7.0_2,1
[ko at wiley ~]$
[ko at wiley ~]$ sudo pkg delete py27-numpy
Package(s) not found!
[ko at wiley ~]$

How do I clean this up?  Thanks.
