[openvrml-develop] Trouble building OpenVRML 0.18.5

[Rich C. <rc...@ll...>]

Hello,
On our clusters, the configure script exits with the following error:

configure: error: in `/usr/global/tools/VRML/OpenVRML/0.18.5/ 
chaos_4_x86_64_ib/openvrml-0.18.5':
configure: error: GIO is required to build OpenVRML Player
See `config.log' for more details.
It appears this is generated by the following code:
configure:21442: checking for GIO
configure:21449: $PKG_CONFIG --exists --print-errors "gio-2.0"
Package gio-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gio-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gio-2.0' found
configure:21452: $? = 1
I did a Google search and this seems to be part of glib, maybe.  I'm  
having trouble figuring out what to ask my sysadmin to install in  
order to make autoconf happy here.  Can someone tell me what RPM is  
missing?  Thanks!
