One way you could solve this problem is to do an `elfdump -Dl
"name-of-program-here"' this will give you a list of libraries. From that list
take the name of the libraries and put them through nm looking for the
undefined symbol or routine. Read the nm man page to see how to tell whether a
symbol is defined or not. Here is an example of what I am talking about....

% elfdump -Dl berfly

Could not find it in any of these libraries so check to see if
XSGIvcQueryChannelInfo is defined in libGL.so .
