Ldconfig

Bonjour a tous
je télécharge kino je 'linstalle et il me dit ca :

checking for execinfo.h... yes
checking for samplerate... Package samplerate was not found in the pkg-config search path.
Perhaps you should add the directory containing `samplerate.pc'
to the PKG_CONFIG_PATH environment variable
No package 'samplerate' found
configure: error: Library requirements (samplerate) not met; consider adjusting
the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard
prefix so pkg-config can find them.
[root@localhost kino-0.7.1]#

Donc je télécharge : libsamplerate-0.1.0.tar.gz

donc je tape en root biensure :
./configure
make
make install
puis ldconfig
mais il m'affiche : bash: ldconfig: command not found

Donc a la place de ldconfig je mets /sbin/ldconfig il m'affiche rien donc je suis reparti dans kino : je recommence ./configure et il me remet
