Perhaps you should add the directory containing `libgnomeui-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libgnomeui-2.0' found

configure: error: Library requirements (libgnomeui-2.0 >= 1.112.0 linc >= 0.5.0 libbonobo-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.

I have slack 8.1 installed.
Please tell me where to find this libraries i need.
