Tried Pokot0's suggestion but ran into an error saying lipcap.so.1 could not be found.
Grabbed
http://ftp6.tw.freebsd.org/FreeBSD/ports/i386/packages-6-stable/net/libpcap-1.1.1.tbz and copied libpcap.so.1.1.1 to /tmp on the device, renamed it to libpcap.so.1.
I'm now getting an error saying Shared object "libsmi.so.2" not found, required by "tcpdump". Still looking for a package that has that file, maybe someone knows how to get it working?
