Can't Install nmap 5.21

[keithnickum@…]

Had an earlier version of nmap installed and had problems with upgrading. The error I'm getting now is a syntax error for setup.py:

/usr/bin/g++-4.0 -L/opt/local/lib -L/opt/local/lib -L/opt/local/lib -Lnbase -Lnsock/src/   -o nmap main.o nmap.o targets.o tcpip.o nmap_error.o utils.o idle_scan.o osscan.o osscan2.o output.o payload.o scan_engine.o timing.o charpool.o services.o protocols.o nmap_rpc.o portlist.o NmapOps.o TargetGroup.o Target.o FingerPrintResults.o service_scan.o NmapOutputTable.o MACLookup.o nmap_tty.o nmap_dns.o  traceroute.o portreasons.o nse_main.o nse_nsock.o nse_fs.o nse_nmaplib.o nse_debug.o nse_pcrelib.o nse_binlib.o nse_bit.o nse_openssl.o nse_ssl_cert.o  -lnbase -lnsock -lpcre -lpcap -lssl -lcrypto libdnet-stripped/src/.libs/libdnet.a liblua/liblua.a -lm

Error: Status 1 encountered during processing.

Here's the general commands I used (more or less, forget the exact details but I *have* done all of these in order, at some point or another). I know some of it is more than a little redundant, but I thought I'd be 100% sure...also, the error is the same error throughout.
