Build failure in Ubuntu 21.04

[Miguel Magán Romero]

Hello all:

I am trying to build PyNE from source in my machine with Ubuntu 21.04, and I have run into this failure in ALPHAD.f:

=======================================

It seems my CMake is configuring Fortran reals as 8-byte by default, and that makes the 0.0 an invalid argument for CNVU2S(). Changing these 0.0 to 0.0_4 allows the code to compile, but I am 99% certain this is an issue in my setup as the reals should be 4-byte. Can anyone help me?
