Perhaps I'm not understanding the whole scenario, but are you trying 
to compile it BSD native, or compile and run it in Linux compatibility mode?

If you're trying to use Linux compatibility mode, you need to make 
sure your session is really running in that mode.  It's been a year+ 
since I tried it, but it wasn't real obvious in the handbook 
IIRC.  You need to get a shell running in Linux mode first;  that 
gets the "union" file system going, so the stuff in /compat/linux is 
"overlayed" on the root filesystem.  The uname command is probably 
the most simple confirmation, eg:

$ uname -a
FreeBSD meddle.xxiii.com 5.4-STABLE FreeBSD 5.4-STABLE #8: Tue Jul 26 
13:28:17 EDT 2005
$ ls /compat/linux/bin
basename        date            ksh             pwd             stty
bash            dd              ln              rm              sync
bash2           echo            ls              rmdir           touch
chgrp           egrep           mkdir           rpm             true
chmod           false           mknod           setserial       uname
chown           fgrep           mv              sh
cp              grep            nice            sleep
$ /compat/linux/bin/bash
bash-2.04$ uname -a
Linux meddle.xxiii.com 2.4.2 FreeBSD 5.4-STABLE #8: Tue Jul 26

Once you have an executable running in compatibility mode (the shell 
in this case), it will search the directory in /compat/linux first, 
and failing that look in the real root system.  So if you type "make" 
and the first directory in your path is /usr/bin, it really looks in 
/compat/linux/usr/bin first, then the real /usr/bin.  I doubt the 
standard Linux mode on FBSD has all the stuff to compile & link 
native Linux code, however.

Hope I'm not re-stating the obvious, but once I figured this out, the 
compatibility mode made a BUNCH more sense.
