In fact the combination of --with-double and static drivers fails on all
platforms that I tested (RH 8.0 and Debian)!  Default configure (which
corresponds to single and static drivers) works fine so that is why we have
been having relatively few (compared to ~3000 downloads) reports on this.

Turned out it was one of those 'obvious' errors.  The STATIC_DRIVERS list is
a list of libtool compiled objects (*.lo) files, and of course there should
be no $LIB_TAG on the name since those aren't shared objects and ultimately
they become part of libplplot[d].so.5.2.0 As soon as I dropped $LIB_TAG from
the STATIC_DRIVERS names (see recent commit of configure.ac) static drivers
worked fine with either single or double.  (They worked fine before for
PLplot-5.2.0 in the single case because $LIB_TAG is empty in that case.)

In contrast the DYNAMIC_DRIVERS are shared objects (*.la files for libtool)
which are installed in the drivers directory.  They must have $LIB_TAG as
part of the name if you want to be able to have both single and double
precision versions of PLplot coexisting at the same time.

I believe dropping $LIB_TAG from the names in STATIC_DRIVERS should take
care of virtually all the errors that have been reported by the users of
PLplot-5.2.0.

The only additional user error reports I can recall involve X problems.
Joao, did that guy who you answered ever come back with the information you
requested?  I have a private report of an additional X problem from somone
else which I will post to this list separately.
