The solution here was rediculously simple, I even found it by myself:
(I re-read the install url again, too :-)

[RadSurfer@centos fortran]$ export
LD_LIBRARY_PATH="/usr/local/gfortran/lib:$LD_LIBRARY_PATH"
[RadSurfer@centos fortran]$ echo ${LD_LIBRARY_PATH}
/usr/local/gfortran/lib:
(this is safe in any event, whether L_L_P already exists or not :-)

[RadSurfer@centos fortran]$ gfortran se2.f95
[RadSurfer@centos fortran]$ ./a.out
