Building erros

[Oscar<Soker>]

I am trying to build amarok from de svn but i'm getting this error

CMake Error: The following variables are used in this project, but they are
set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake
files:
LIBLASTFM_INCLUDE_DIR (ADVANCED)
   used as include directory in directory
/home/oscar/amarok/src/services/lastfm
LIBLASTFM_LIBRARY (ADVANCED)
    linked by target "amarok_service_lastfm" in directory
/home/oscar/amarok/src/services/lastfm
    linked by target "kcm_amarok_service_lastfm" in directory
/home/oscar/amarok/src/services/lastfm

-- Configuring incomplete, errors occurred!

Any ideas???
