Look again. The installed infoagents version of netscape now LD_PRELOADs
gnumalloc.so. The problem Emil is referring to is that gnumalloc.so
is not compatable with old versions of libc. We could either tell
users to upgrade or somehow figure out which version of libc 5
they're using and only do LD_PRELOAD if it's newer than 5.2 (ewww).
