Comment (by jmroot):

 Cf. #21082, #39850. In short, things get really confusing when the prefix
 is not a fully resolved and normalised path. Whether the normalised or un-
 normalised version is created in the destroot, anything not checking for
 both will potentially get it wrong. I would guess the glob in the python
 portgroup is just not matching anything.

 You probably don't need to reinstall base since you're not actually moving
 any files, just update macports.conf to use the resolved path for
 everything.
