I get the following error when running make on Linux Mint running on Hewlett Packard Compaq nc6320:

dde@alpha:~/wspr$ make
gfortran -c wspr2.f90
wspr2.f90:68:23:

call random_seed(PUT=iclock)

Error: Size of ‘put’ argument of ‘random_seed’ intrinsic at (1) too small (12/33)
Makefile:92: recipe for target 'wspr2.o' failed
make: *** [wspr2.o] Error 1

Can anybody help?
Thank you.
