ENSURE-PATHNAME uses PARSE-UNIX-NAMESTRING, not PARSE-NAMESTRING.
In this case, you want PARSE-NAMESTRING (possibly through PATHNAME).
(describe (uiop/pathname:ensure-pathname "home:lisp;asdf;"))
#P"home:lisp;asdf;" is a pathname, with the following components:
NAME = "home:lisp;asdf;"
VERSION = :NEWEST
(Also, most of the time that you use MERGE-PATHNAMES, you should probably
instead be using UIOP:MERGE-PATHNAMES* or UIOP:SUBPATHNAME.)

CLHS pathnames are strange and shaky. UIOP tries to paper over the issues,
making them notably less shaky and the price of being a bit stranger.

First they ignore you. Then they laugh at you.
Then they fight you. Then you win.
