(Others can correct me, but I don't think LD_LIBRARY_PATH is relevant here.)

One thing that looks suspicious is the weird order of linking: (from the
log file):

gfortran -O3 -mtune=native -DCUDA -o pmemd.cuda gbl_constants.o
gbl_datatypes.o state_info.o file_io_dat.o mdin_ctrl_dat.o mdin_ewald_dat.o
mdin_debugf_dat.o prmtop_dat.o inpcrd_dat.o dynamics_dat.o img.o nbips.o
parallel_dat.o parallel.o gb_parallel.o pme_direct.o pme_recip_dat.o
pme_slab_recip.o pme_blk_recip.o pme_slab_fft.o pme_blk_fft.o pme_fft_dat.o
fft1d.o bspline.o pme_force.o pbc.o nb_pairlist.o nb_exclusions.o cit.o

shake.o prfs.o mol_list.o runmin.o constraints.o axis_optimize.o gb_ene.o

nmr_lib.o get_cmdline.o master_setup.o pme_alltasks_setup.o pme_setup.o
ene_frc_splines.o gb_alltasks_setup.o nextprmtop_section.o angles_ub.o
dihedrals_imp.o cmap.o charmm.o charmm_gold.o findmask.o remd.o multipmemd.o
remd_exchg.o amd.o \
      -L/usr/local/cuda/lib64 -L/usr/local/cuda/lib -lcurand -lcufft -lcudart
./cuda/cuda.a -L/home/jonathan/amber12/lib -L/home/jonathan/amber12/lib
-lnetcdf

For machines that link based on order, it may be that the ./cuda/cuda.a
reference should come *before* the cuda libs, not after them. Try
editing the PMEMD_CU_LIBS variable in your config.h file to but the
"./cuda/cuda.a" part first rather than last.

No guarantees at all, but it's a simple thing to try, and might help.
