glug: installazione di xoscope

[bruno]

Gent.

vorrei utilizzare xoscope-1.10 (programma che simula un oscilloscopio
utilizzando una scheda audio);
ho scompattato ed installato regolarmente comedilib.
Ho scompattato xoscope-1.10.tar.gz e lanciato ./configure;
il risultato e' l'errore sotto indicato

configure: error: Cannot find GTK: Is gtk-config in path?
---------------------------------------------------------
a me pare di avere gtk installato ma non risulta al mio sistema Fedora
2A.
Mi potete suggerire i controlli da effettuare?
Grazie per l'aiuto
