This directory is normally empty (until you untar galdata.tgz in there,
that is).

1) If your version is relatively recent (>= 2.1.1), you can set the environment
variable GP_DATA_DIR to point to an arbitrary directory (used as 'datadir').
['man gp' will tell you about it if it's available]. Then the hardcoded
default doesn't matter anymore.

2) Otherwise, check for 'datadir' in dft.Config.in if you can locate it.

3) Otherwise, locate paricfg.h and look for GPDATADIR

4) A desperate solution if nothing above works :

a) locate the libpari corresponding to your gp-dyn binary [or the gp binary
itself if you did not install any library; which is presumably the case since
paricfg.h was not found].

b) look for absolute paths in there.

On my machine:

(17:48) geo-karim% strings $HOME/lib/libpari-2.2.so | grep '^/'
/home/belabas/GP/lib/pari/galdata
/bin/gzip -dc
/tmp
/var/tmp
/@2@

Here, number 1 is the obvious candidate.
