I went back to first principles, recompiled and spotted an error
message -- it seems that incm.c for mew4 is in C++ and gcc was
treating it as C ( I know nothing about either ).  I renamed
incm.c to incm.cc and recompiled without error then reinstalled.

Still incm empties /var/spool/mail/fgs but the mail dissappears.

I ran strace as you suggested and to my untutored eye the
following lines seem to be indicative of a problem:

open("/etc/ld.so.preload", O_RDONLY)    = -1 ENOENT (No such file
or directory)
.
.
stat64("/home/fgs/Maildir", 0xbffff550) = -1 ENOENT (No such file or directory)
.
.
.
access("/var/run/utmpx", F_OK)          = -1 ENOENT (No such file or directory)
open("/var/run/utmp", O_RDWR)           = -1 EACCES (Permission
denied)
.
.

open("/dev/null", O_RDONLY|O_NONBLOCK|O_DIRECTORY) = -1 ENOTDIR (Not a directory)



I guess I have pretty well reached the end of my knowledge ( or
way beyond it ).


Thanks
