Indeed, we have two packages called “python-wrapper”, a mistake from
95288fc.

This is fixed with:

diff --git a/gnu/packages/python.scm b/gnu/packages/python.scm
index 95c24a6..e81e251 100644
--- a/gnu/packages/python.scm
+++ b/gnu/packages/python.scm

-(define* (wrap-python3 python #:optional (name "python-wrapper"))
+(define* (wrap-python3 python
+                       #:optional
+                       (name (string-append (package-name python) "-wrapper")))
   (package (inherit python)
     (name name)
     (source #f)

However, this entails a big rebuild, so this will have to go to
‘core-updates’.

In the meantime, I would recommend using -e to unambiguously refer to
the right wrapper.  Otherwise, we could come up with workarounds, such
as keeping the ‘python-minimal-wrapper’ private.

Thoughts?
