Perhaps you should add the directory containing `libxml-2.0.pc'
to the PKG_CONFIG_PATH environment variable
Package 'libxml-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.
