How-to not get a "depency resolution failed" for a already existing library.

[L Pierre]

Hi,

I've been struggling a few days now to create an installable rpm and no joy.

On installation I get "Dependency resolution failed" message: "libsemnoteslib.so is needed by package plasma-semnotes-0.3.0-1.fc10.i386 (/plasma-semnotes-0.3.0-1.fc10.i386)" although the library does reside on /usr/lib

What I need: I need to install my application that uses a library "libsemnoteslib.so". This library already resides in /usr/lib/. The library should not be installed by my rpm.

Then, as enhancement,it would be nice to just check it the library exists on /usr/lib if not, do not install otherwise install.

I create the rpm perfectly, but during install I get this error.

How do you do this simple task?
