LYNX-DEV Solaris /usr/ucb/* mystery Saving to disk

[Paul Gilmartin]

When I attempt to download with the "Save to disk" option,
I get a failure with the trace:

    LYGetFile: getting 
LYNXDOWNLOAD://Method=-1/File=/tmp/L264491TMP.html/SugFile=htt
p:--www.mklinux.apple.com-
 
    HTParse: 
aName:LYNXDOWNLOAD://Method=-1/File=/tmp/L264491TMP.html/SugFile=http:--
    www.mklinux.apple.com-   relatedName:
    HTParse: result:Method=-1
    command: /bin/cp /tmp/L264491TMP.html 
'/home/pg/http:--www.mklinux.apple.com-'
    sh: /usr/ucb/cp: not found
 
The trace output immediately before the "system" call says it's using
"/bin/cp", but the error message from "system" says it can't find
"/usr/ucb/cp".  A similar error occurs when it tries to delete the
temporary file -- it can't find "/usr/ucb/rm".

The error occurs running Lynx 2.7.1 on a Solaris 2.5.1 system.  Running
the same binary of Lynx on a SunOS 4.1.3 system, I get no error.

What's going on here?  Is this some weirdness inflicted on me by
Solaris/Sun binary compatibility?  Does Lynx front-end "system"
and modify the path?

Curiously,
