issue compiling runeems_snps on linux

[adamfreedman]

I was obliged to rebuild my eems install after our HPC was refactored. Fwiw, I've run it succesfully before. That said after having modified the makefile to point to relevant boost and eigen3 directories (which are nested inside a conda environment), make linux yields errors upon "make linux" (we're running on rocky)

Not sure what is going on here
