[Openmcl-devel] Probe-file returns a file, load fails!

[Gary Byers]

I don't know if it's a factor, but sometimes when pathname operations
give puzzling, inconsistent results it's worth checking the value of
*DEFAULT-PATHNAME-DEFAULTS*; things are often more tractable when
it's an empty pathname (#P"").  If it -is- a factor, it may or may
not be affecting things correctly.

If it's not a factor in your case, it might be interesting to trace
PROBE-FILE before calling LOAD, to see what (transformed) pathname
LOAD's concluding doesn't exist.
