Missing pathnames features
The following features are missing from Medley's implementation of Common Lisp pathnames:
-
#preader macro -
:absoluteand :relativedirectory components
This was discovered when evaluating the compatibility of Medley Common Lisp with ANSI Comon Lisp in issue #609, specifically by testing the files and I/O code of the book Practical Common Lisp.
You might want to try loading CMLPATHNAME from the CLtL2 directory and see if that solves it.

As far as I know the CLtL2 directory is missing from Medley Online, so I downloaded the file from the repo and uploaded it. But, when loading CMLPATHNAME.LCOM from a XCL Exec, most of the times I get a break window with the error External symbol LOGICAL-PATHNAME not found in package LISP:
When the break window doesn't open and I evaluate a #p expression such as #p"file.txt" I get the same error Undefined dispatch character #\P for dispatch macro character #\#.
I’m not sure any of the compiled files in the CLtL2 directory have been compiled with a modern image, for anything in there I would go with the source files. But in this case I suspect there’s another dependency involved. The packages in CLtL2 are different from 1, and that symbol is probably defined elsewhere.

CL:LOGICAL-PATHNAME is defined in the CMLPATHNAME source file both as DEFSTRUCT (line 43) and as DEFUN (line 193)
There are package problems with the CLTL2 files.. the COMMON-LISP package is built specially before packaging is enabled see PACKAGING-ENABLE
