You didn't say what system this is on.
This doesn't happen to me; I'm running "vic" on a NetBSD/SPARC 1.0 system:
isolar:1:37 % rsh -n netbsd4me ldd /usr/local/bin/vic
ldd: /usr/local/bin/vic: not a dynamic executable
isolar:1:38 % rsh -n netbsd4me "setenv DISPLAY isolar:0.0 ; \
setenv LD_TRACE_LOADED_OBJECTS 1 ; /usr/local/bin/vic"
vic: warning: not using shared memory
vic: destination address required
Note that as of the 1.0 final release (i.e., not -current), you can't use the
dynamically-linked version (i.e., that uses libg++.so.2.0) because it core
