Can't set build lock for symlinks (1.2-2)

If any of the above dpkg error messages mention conflicting packages or missing
dependencies -- for example, telling you that the package fink-buildlock-symlinks-1.2-2
conflicts with something else -- fink has probably gotten confused by trying  to build
many packages at once. Try building just this current package symlinks (i.e, "fink build
symlinks"). 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.
