It turns out that this question has already been answered:

It turns out the fatal combination is static drivers and --with-double on
*all* platforms.  (We gave the mistaken impression before this problem on=
ly
occurred on some platforms.) Thus, for any platform a workaround is to
specify --enable-dyndrivers.  An alternative workaround is to avoid
specifying --with-double.  Its a Boolean OR of those two workarounds. Thu=
s,
the combination of --enable-dyndrivers and --with-double builds fine sinc=
e
the first workaround condition is fulfilled.  Similarly, default options
(nothing specified about the kind of drivers or precision) build fine sin=
ce
the second condition is fulfilled.

This question was also already answered (not a plplot issue): you have to=
 use=20
xauth in order to securely run Tk (as tk has a mechanism that would allow=
=20
others to execute commands on your computer -- no need to be a hacker).
The easier way to setup xauth is to use a xdm login manager, like xdm, kd=
m,=20
etc. Otherwise you must use the xauth program and *do not* enable xhosts.=
=20
Other possibility is to rebuild tk without security.

Thanks,
Joao
