Part1 of the problem has an explanation: The code searches for the files not
in "/usr/share/plplot...", but in "share/plplot..." (and /usr/local as
last resort) ! This insane:

3869:   open("cmap0_default.pal", O_RDONLY)             Err#2 ENOENT
3869:   open("share/plplot5.13.0/cmap0_default.pal", O_RDONLY) Err#2 ENOENT
3869:   open("/usr/local/plplot/lib/cmap0_default.pal", O_RDONLY) Err#2 ENOENT

*** PLPLOT WARNING ***
3869:   write(2, "\n * * *   P L P L O T  ".., 24)      = 24
Unable to open cmap0 file cmap0_default.pal
3869:   write(2, " U n a b l e   t o   o p".., 44)      = 44

3869:   write(2, "\n", 1)                               = 1
3869:   open("cmap0_default.pal", O_RDONLY)             Err#2 ENOENT
3869:   open("share/plplot5.13.0/cmap0_default.pal", O_RDONLY) Err#2 ENOENT
3869:   open("/usr/local/plplot/lib/cmap0_default.pal", O_RDONLY) Err#2 ENOENT

linking /usr/share into the working directory lets it find the files,
but still the plplot xwin driver is not found:

GDL> plot,findgen(100)

*** PLPLOT ERROR, ABORTING OPERATION ***
plInitDispatchTable: Could not open drivers directory, aborting operation
% PLplot installation lacks the requested driver: xwin
% Execution halted at: $MAIN$
