I have downloaded g2ipmsg from  http://www.ipmsg.org/archive/g2ipmsg-0.9.6.tar.gzWhile installing this package, it is causing some error. checking for G2IPMSG... configure: error: Package requirements (libgnomeui-2.0 >= 2.14                gtk+-2.0 >= 2.4                glib-2.0 >= 2.8) were not met:    No package 'libgnomeui-2.0' found    Consider adjusting the PKG_CONFIG_PATH environment variable if you    installed software in a non-standard prefix.    Alternatively, you may set the environment variables G2IPMSG_CFLAGS    and G2IPMSG_LIBS to avoid the need to call pkg-config.    See the pkg-config man page for more details.How to resolve this error please let me know.

Ensure that you have the package libgnomeui-2.0 mentionned into the error message correctly installed. Depending of your distribution, use apt-get or yum to install it.You may also need to install gtk+-2.0 and glib-2.0 (install first package and check the updated error message if any).
