Errors were encountered while processing:
 fink-buildlock-gnupg-1.4.0-2
### execution of dpkg failed, exit code 1
Can't set build lock for gnupg (1.4.0-2)

If any of the above dpkg error messages mention conflicting packages --
for example, telling you that fink-buildlock-gnupg-1.4.0-2
conflicts with something else -- fink has probably gotten confused by trying 
to build many packages at once. Try building just this current package
gnupg (i.e, "fink build gnupg"). When that has completed successfully, 
you could retry whatever you did that led to the present error.

Regardless of the cause of the lock failure, don't worry: you have not
wasted compiling time! Packages that had been completely built before
this error occurred will not have to be recompiled.
