'iscan' by itself from a cli doesn't return anything within a minute 
or so.  The scanner does move ever so slightly, but the lamp doesn't 
come on, and I eventually ctrl-c'd it.

Yes.

/usr/local/bin/iscan

The epkowa.conf was installed in /usr/local/etc/sane.d, after modding 
it for usb rather than parport.

All backends appear to be installed in /usr/local/lib/sane, and the 
epkowa stuff looks like this in there:
[root at coyote root]# ls -l /usr/local/lib/sane/*-epkowa.*
-rw-r--r--    1 root     root       376302 Aug  1 07:08 
/usr/local/lib/sane/libsane-epkowa.a
-rwxr-xr-x    1 root     root          822 Aug  1 07:08

/usr/local/lib/sane/libsane-epkowa.so.1.0.6

Are those perms correct?

Humm, from the cli, "xsane" leaves this behind:
[root at coyote root]# xsane
[epson] Could not find "libesint1F.so".

But
[root at coyote root]# locate ibesint1F.so
/usr/local/lib/libesint1F.so.1.0.0
/usr/local/lib/libesint1F.so.1
/usr/local/lib/libesint1F.so
/usr/src/iscan-1.5.2/esint1F/libesint1F.so
/[root at coyote root]# ls -l `locate libesint1F`

Wrapping that up in an ls -l shows
[root at coyote root]# ls -l `locate libesint1F`
lrwxrwxrwx    1 root     root           19 Aug  1 07:08 
/usr/local/lib/libesint1F.so -> libesint1F.so.1.0.0
lrwxrwxrwx    1 root     root           19 Aug  1 07:08 
/usr/local/lib/libesint1F.so.1 -> libesint1F.so.1.0.0
-rwxr-xr-x    1 root     root       470129 Aug  1 07:08 
/usr/local/lib/libesint1F.so.1.0.0
-rwxr-xr-x    1 root     root       159836 Jan 21  2003 
/usr/src/iscan-1.5.0/esint1F/libesint1F.so
-rwxr-xr-x    1 1000     1000       470129 Jun 23 05:34 
/usr/src/iscan-1.5.2/esint1F/libesint1F.so

and an echo of LD_LIBRARY_PATH as exported by that same shell is:
[root at coyote root]# echo $LD_LIBRARY_PATH
/usr/local/lib:/usr/local/lib/sane:/root/kde3.1.1/lib:(repeat last 
path entry about 10x times, no idea why)

Humm, that I did. 1.5.2 is the first one that would actually build for 
me, all earlier ones died on the pisa stuff in the gui.  But that was 
after the libs were built, so a make install would put enough stuff 
in that xsane could find it and use it ok back at one of the earlier 
sane versions.

I did that(installed the object rpms), but then recalled that since 
sane is built from tarballs, then iscan should be too & tried to have 
rpm rip it out, but rpm gave me a weird malloc fail error like maybe 
its rebuilddb time.  So I just fired that off for grins as thats the 
second time I seen that error recently.  Amanda will probably 
complain :)

Yes

And I hope this is enough clues to name the perp. :-)
