Possible problem with Natty 64-bit compile

[Susan Cragin]

I have downloaded the git, compiled and installed wine as 64-bit on the current 64-bit version of Natty. 
This all works fine, no errors I can see, but then it doesn't run. 
My executables can be found, including: 
/usr/local/bin/wine64 and wine64-preloader
But I can't run anything. A "wine" command tells me wine isn't installed, which I guess it isn't, and "wine64" gives me a segmentation fault. 
Do I need a symlink? 

ubuntu$ wine notepad
The program 'wine' can be found in the following packages:
 * wine-bin-unstable
 * wine1.2
 * wine1.0
Try: sudo apt-get install <selected package>
ubuntu:~$ wine64 notepad
Segmentation fault
ubuntu:~$
