Pierre,

please note that cmake seems to store a list of files installed by the
package, which broke cmake-using dependents of clang when we attempted
to change the set of files installed: http://issues.guix.gnu.org/41872

Did you try building something that depends on LLVM and uses
cmake-build-system?
