Says the most important driver for plplot, xwin, is not compiled

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

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

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: $MAIN$
GDL>
And so the second part has the same embarassing explanation:
3874: open("lib/amd64/plplot5.13.0/drivers", O_RDONLY|O_NDELAY|O_LARGEFILE)
Err#2 ENOENT
Also linking /usr/lib/ into the current working finally lets it find its driver
library, too....
Please can somebody recompile plplot with proper fixes to stop this madness ?
It seems that, at compile time, some variables were not set correctly
(aka, empty):
<http://plplot.sourceforge.net/docbook-manual/plplot-html-5.13.0/deploying.html>
" In the first case the program will contain all the code it needs to work, but
to run successfully, it needs to find the font files, plstnd5.fnt and
plxtnd5.fnt. The mechanism used in PLplot to find these files is fairly simple:
It looks at a number of built-in places, determined at the time the PLplot
library itself was installed and built. For deployment these places are
irrelevant in general.
It looks at the environment variables PLPLOT_LIB and PLPLOT_HOME.
vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
(Actually, this happens only, if the corresponding compiler macros
PLPLOT_LIB_ENV and PLPLOT_HOME_ENV were defined at compile time.) "
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The compile time variables were set, because plplot reacts to PLPLOT_LIB.
But the default directories were not set.
Actually, setting the runtime variables to the default directories helps
as a first workaround:
setenv PLPLOT_LIB /usr/share/plplot5.13.0
setenv PLPLOT_DRV_DIR /usr/lib/amd64/plplot5.13.0/drivers
and GDL (and probably other programs linked to plplot) can finally plot !
