[Hat] 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? Bob
