Problems compiling app-text/poppler-bindings-0.8.7

Hace algunos días trataba de compilar el paquete "app-text/poppler-bindings-0.8.7" pero me arrojaba el siguiente error en la compilación:

0015 Consider adjusting the PKG_CONFIG_PATH environment variable if you
0016 installed software in a non-standard prefix.
0017
0018 Alternatively, you may set the environment variables POPPLER_QT4_CFLAGS
0019 and POPPLER_QT4_LIBS to avoid the need to call pkg-config.
0020 See the pkg-config man page for more details.

Cabe mencionar que usaba el administrador "Portage" (para los que no sepan algo como el "apt-get", "yast", etc, a diferencia que este descara el código fuente y lo compila).

Por fin pude compilar ese paquete, basta con incluir en la compulacion qt-4 y poppler-bindings en la misma llamada de emerge-
