LAPACK/ScaLAPACK Development

Hi, everyone

I'm a newbie to lapack, today I just installed (I'm not sure successful or not, but I didn't have errors when I type those 'makes' as the installation guide said.) So, anyway, back to my question, I installed Lapack in Ubuntu with gfortran, and first when I untar the .tgz installation file, I untared it at /home/Lapack directory. So after installation, here is the file I got:

/home/Lapack: blas_LINUX.a, lapack_LINUX.a, tmglib_LINUX.a
/usr/local/lib: libblas.a
/usr/lib/atlas: libblas.so.3 and liblapack.so.3 , I think these two files came with ubuntu and were there before I install Lapack, although I'm not sure.

Ok, so now I'm not sure I have everything I should have and is it enough for me to call lapack subroutines now. But first problems is: after I write two small fortran programs, main.f90 and call.f90, in call.f90 I called the subroutine dgemv to solve the linear equation. But I don't know what the makefile should be like so that I can compile through, obviously I need to do some linking with Lapack library, did I?

So for anyone who finished reading my this messy post, I really appreciated, If you happen to know how to solve this problem, please do reply it, thank you very much in advance.
