Thanks for the suggestion! Unfortunately this gets me a value of
`SCSH_LIB_DIRS' like

    /home/chelys/.guix-home/profile/share/scsh-0.7

which, when I try the command `scsh -ll mpd.scm -o mpd' causes the
following error to appear:

    error: Illegal path element in $SCSH_LIB_DIRS
    $SCSH_LIB_DIRS: /home/chelys/.guix-home/profile/share/scsh-0.7
    The following element is not a string or #f: /home/chelys/.guix-home/profile/share/scsh-0.7

It's because SCSH treats the contents of `SCSH_LIB_DIRS' as "a sequence
of of s-expressions, which are `read' from the string"[1] and supports
either string values or the value #f. So `SCSH_LIB_DIRS' would have to
be in this case:

    "/home/chelys/.guix-home/profile/share/scsh-0.7"

I guess this just isn't supported as yet in Guix?


Cheers,

Tom
