zypper : "nothing provides " but exists

Hi,
I have created a rpm (cmake, cpack) that when installed with zypper resolvs and installs the dependencies.
But now with a new lib ( /usr/lib64/libRInside.so ) linked ,in the C++ program, zypper is not able to resolv and install and finally stops without installing.

Info here :

///////// The lib exits.
#ls /usr/lib64/libRInside.so
/usr/lib64/libRInside.so

///////// The package is installed.

Problem: nothing provides libRInside.so()(64bit) needed by myPkg-0.4.master.4661920-1.i686
Solution 1: do not install myPkg-0.4.master.4661920-1.i686
Solution 2: break myPkg-0.4.master.4661920-1.i686 by ignoring some of its dependencies

Any clues?

Thank you.
