Hi Alexis:

I am joining this conversation late because I couldn't participate
earlier (incoming mail-chain troubles that are now fixed).  I am also
CCing Orion since he is very experienced at dealing with PLplot issues
on Fedora. (He maintains the Fedora rpms for PLplot.)

Coincidentally, I have just finished (see my latest post to the
plplot-devel list) a big effort on improving the parts of the build
system having to do with Tcl, Tk, Itcl, Itk, and Iwidgets.  The result
is more demanding of consistency for all components and also more
verbose about what it finds.  So I would appreciate you giving the
plplot svn trunk version a try to see if (a) it works on your
Fedora system, and (b) it is verbose enough for you.

That version also has Arjen's fix concerning TclFormatInt.  I am
virtually positive the fundamental issue there is the PLplot build
historically relied on "private" Tcl headers. In 2000 or so when I was
still building PLplot on a RedHat platform, I ran into a lot of such
issues which Maurice (our Tcl/Tk guru who has mostly retired from
working on PLplot now) fixed at the time.  But after I switched to
Debian (whose Tcl devel package includes all private headers) a few of
these issues may have crept back (because Tcl developers likely made
different decisions about what was private and what not). So Arjen's
fix is a good step in the right direction, and if you now try the svn
trunk version of PLplot on Fedora you may find all is well now with
the Tcl component of the build.  Or you might run into a few more
private header issues which we would be happy to fix if you were
willing to do the necessary build experiments.

I also have access to a Tcl8.6 build I have done myself which I am
currently using to test PLplot's Tcl8.6 capabilities.  I notice that
build has a switch that can be used to turn off the install of private
headers.  So now you have reminded me of the private header issue with
Tcl, I plan to use that switch to see if there is anything more to
deal with.
