Problem with installing/running executables

[Pdkilllourhy00 at aol.com]

Hi; I've just installed FreeBSD 5.1-RELEASE/i386 and am having a problem with 
the shell finding
executable files as valid commands. 

This is an example of the problem I have:
> su root
Password:
# cd /usr/local/apache2/bin
# ls -l a*
-rwxr-xr-x   1 root   wheel   74207 Jan 11 19:13 ab
-rwxr-xr-x   1 root   wheel    5360 Jan 11 19:05 apachectl
-rwxr-xr-x   1 root   wheel    8911 Jan 11 19:13 apr-config
-rwxr-xr-x   1 root   wheel    8108 Jan 11 19:13 apu-config
-rwxr-xr-x   1 root   wheel   24808 Jan 11 19:05 apxs
# ./apxs
./apxs: Command not found.

I'm at a complete loss, any help anyone can give would be appreciated. 
Thanks!
