Is there an advisable way to upgrade a /usr/pkgsrc tree created
with the 1.3.2 release ?

The packages ImageMagick and fly won't build. In the case if ImagMagik
the orginal tgz file has be replaced with a new release 4.0.6 but my
installation needs 4.0.5. and in the case of fly the md5 checksum
dosen't match. Presumeably these problems would be solved by user the
-current release of pkgsrc but will it causes and confusion with the
packages already installed.
