You have not divulged which Lisp you are using. With AllegroCL, if I 
open a project and happen to open a source file or two before compiling 
anything, the ACL IDE interns symbols as it finds them, and does so in 
my package because that is the only one it sees (well, aside from the 
packages it ships with, including common lisp. But it would not know 
about the LTk package until I compiled the whole project.)

Thus the solution is to start your Lisp, build your project (perhaps 
with ASDF), and then start poking around.

btw, the warning you are getting probably offers a restart to "unintern 
conflicting symbols" or some such and you can use that to remove the 
conflicts, but there is a gotcha: any source compiled thinking the 
symbol was in your package still needs to be recompiled. Uninterning 
just cleans up the packages, not your FASLs.
