Yes, if you have installed any 32-bit shared libraries it requires.

As you can see, you need the 32-bit header versions here. Not that I 
have any personal desire to mess with an application which includes 
stub.h. Ubuntu handles the coexisting 32- and 64-bit headers and 
libraries contrary to accepted schemes, so you take on this 
responsibility yourself when you choose Ubuntu.   Normally, you wouldn't 
take your 32-bit installation one library and one header at a time; you 
would install all the 32-bit development and compatibility libraries 
provided by your distro as a starting point.
