error: Failed dependencies: but libraries are installed

[myken]

Hello,

Sorry if this has been asked before, I couldn't find a meaningful answer 
searching.
I need some help installing a package from Lattice 
(http://www.latticesemi.com). Lattice provides a linux x86_64 rpm 
package but I have some difficulties installing it.

If I run:
rpm --test -Uvh diamond_2_2-base_x64-101-x86_64-linux.rpm
I get:
error: Failed dependencies:
     /bin/csh is needed by diamond_2_2-base_x64-2.2-101.x86_64
     /bin/ksh is needed by diamond_2_2-base_x64-2.2-101.x86_64
     libXi.so.6 is needed by diamond_2_2-base_x64-2.2-101.x86_64
     libXrender.so.1 is needed by diamond_2_2-base_x64-2.2-101.x86_64
     libXtst.so.6 is needed by diamond_2_2-base_x64-2.2-101.x86_64
     ... etc ....

To illustrate my problem I will use libXi.so.6 as an example, but all 
failed dependencies are available on my system.
When I run:
whereis libXi.so.6
I get:
libXi.so: /lib64/libXi.so.6 /lib64/libXi.so /usr/lib64/libXi.so.6 
/usr/lib64/libXi.so

and if I run:
yum list installed | grep libXi
I get:
libXi.x86_64 1.6.2.901-1.fc18                   @updates
libXi-devel.x86_64 1.6.2.901-1.fc18                   @updates
libXinerama.x86_64 1.1.2-5.20130524git99c644fc8.fc18  @updates
libXinerama-devel.x86_64 1.1.2-5.20130524git99c644fc8.fc18  @updates

and if I do:
rpm -qa | grep libXi
I get the same installed libraries:
libXinerama-1.1.2-5.20130524git99c644fc8.fc18.x86_64
libXi-devel-1.6.2.901-1.fc18.x86_64
libXinerama-devel-1.1.2-5.20130524git99c644fc8.fc18.x86_64
libXi-1.6.2.901-1.fc18.x86_64

So as far as I know there shouldn't be a dependencies problem, but I'm 
missing something and I can't figure out what.
Any help is very much appreciated.

Thanks, Robert.
