Sorry to keep banging on about this, but I can't help feeling that
somebody must know the answer!

My .guile file reads:

(use-modules (ice-9 readline))
(activate-readline) 

I find the following:

1)

If I run 'lilypond scheme-sandbox' I get a message saying:

/usr/local/lilypond/usr/share/lilypond/current/ly/scheme-
sandbox.ly:3:2: error: GUILE signaled an error for the expression
beginning here
#
 (load-user-init)
readline is not provided in this Guile installation

In 'top' I can see that the actual running command is
'/usr/local/lilypond/usr/bin/lilypond scheme-sandbox'.

2)

If I run '/usr/local/lilypond/usr/bin/lilypond scheme-sandbox' directly
from the command line, I get guile complete with readline.


This doesn't actually matter too much now that I have discovered that
the longer form of the command works as expected, even though the
shorter one doesn't.

But how is it that I get different results from two command line
entries which end up running the same actual command?
