sound-juicer

[thrashera]

estou com uma duvida na instalação do sound-juicer, ocorre o seguinte erro:

checking for BURN... configure: error: Package requirements (libbrasero-media >= 0.9.1) were not met:

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
Package 'gtk+-2.0', required by 'libbrasero-media', not found

a biblioteca libbrasero ja está instalada, configurei a variavel de ambiente pkg_config_path e mesmo assim retorna este erro.

oq eu faço??
