This modified error reporting seems reasonable to me, but I haven't tested
it.  It only being for the "new" guile 3.0 is probably fine.  IIUC, within
the build environment, guile 3.0.SOMETHING is used, and configure.ac
only checks for guile 3.0:

dnl Search for 'guile' and 'guild'.  This macro defines
dnl 'GUILE_EFFECTIVE_VERSION'.
GUILE_PKG([3.0])
GUILE_PROGS
if test "x$GUILD" = "x"; then
   AC_MSG_ERROR(['guild' binary not found; please check your Guile installation.])
fi
