Problems identifying libXmHTML.so.1.1

[Lance Hoffmeyer <lanceh@ibm.net>]

Everytime I try installing a file (tar or deb) I get an error
message            

ldconfig: warning: can't open /usr/X11R6/lib/libXmHTML.so.1.1 and
ldconfig: warning: can't open /usr/X11R6/lib/libhttp.so.0.1

but I checked and both of these files are in the directory.

So, why will they not be recognized or opened and what can I try to
correct this?

Thanks

Lance
