config appears to have gone crazy

Something appears to have blown up in configuring hat on my box...  
The release used to work, but I just checked out of cvs, built  
cleanly, and now get this when I try to run any of the tools:


tatd2@jet ~/HatDeltaExample $ hat-observe
/usr/local/bin/hat-observe: line 4: /usr/local/bin/harch: No such  
file or directory
/usr/local/bin/hat-observe: line 5: /usr/local/lib/hat//hat-observe:  
No such file or directory
/usr/local/bin/hat-observe: line 5: exec: /usr/local/lib/hat//hat- 
observe: cannot execute: No such file or directory

It appears to have decided the architecture is '', rather than 'ix86- 
linux'.

Any ideas?
