I am running Ubuntu 10.10 on an AMD Athlon X2 64 bit laptop

When I follow the instructions and do

   CFLAGS="-O3 -Wall -msse2" ./configure
   make

it runs fine and produces minerd as an executable.

But when I run it I get this

cdnbcguy@hiscomputer:~/cpuminer-0.8.1$ minerd
No command 'minerd' found, did you mean:
 Command 'mined' from package 'mined' (universe)
minerd: command not found

What the problem, please?
