[Ubuntu-BR] Problemas GTK

[Adilson de Oliveira]

Boa Noite pessoal

Preciso instalar um programa e estou tento um problema no comando 
./configure ele da um erro:

 checking for gtk+-2.0 >= 2.0.0... Package gtk+-2.0 was not found in the 
pkg-config search path. Perhaps you should add the directory containing 
`gtk+-2.0.pc' to the PKG_CONFIG_PATH environment variable No package 
'gtk+-2.0' found
configure: error: Library requirements (gtk+-2.0 >= 2.0.0) not met; 
consider adjusting the PKG_CONFIG_PATH environment variable if your 
libraries are in a nonstandard prefix so pkg-config can find them.

Alguém sabe como posso configurar o pkgconfig para encontrar o gtk?
