swig~pkg-renamed-XXX prevents upgrading swig

[Xavier]

Hi,

I cannot upgrade/reinstall swig (1.3 & 2.0) because a package name change :

| [root at valinor ~]# portupgrade -vf devel/swig20
| --->  Session started at: Sun, 25 Jan 2015 19:58:08 +0100
| [Reading data from pkg(8) ... - 650 packages found - done]

	! devel/swig20 (swig~pkg-renamed~5AF8-2.0.12_1)	(backup error)

However these packages are registered :

| [root at valinor ~]# pkg info swig\*
| swig~pkg-renamed~5AF8-2.0.12_1
| swig~pkg-renamed~8A1C-1.3.40

But cannot be deleted :

| [root at valinor ~]# pkg delete -f swig~pkg-renamed~5AF8-2.0.12_1
| Checking integrity... done (0 conflicting)
| Package(s) not found!

Many thanks for any help.
