lang/python23 has a patche to configure for bdb support that do a very evil thing.  It looks at BUILDLINK_TRANSFORM in order (I think) to know if a library is needed, and which.

This is evil, because teaching the package about an internal bit of pkgsrc is already wrong, and also because the purpose of BUILDLINK_TRANSFORM is to make the wrappers change on-the-fly the library name to the correct value.

However, the reason it breaks on Linux is because the db1 library is named  Thus, while BUIDLINK_LDADD.db1 is not empty (-ldb), BUILDLINK_TRANSFORM is because the library is already named libdb.  That later leads to a linking failure, which goes unnoticed because of the tolerant nature of python's build system.  But pkg_create sure does complain about the missing modules and the incorrect PLIST.

And anyway, why not simply use BDB_LIBS?  I tried that (patch not included, but it's trivial) and it Just Works on my system.
Build python23 on a system where the library for db1 is named
