checking for GGOBI... configure: error: Package requirements (ggobi >=
2.1.6) 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 'libggobi', not 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 GGOBI_CFLAGS
and GGOBI_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
