[Plplot-devel] linking, build issues

[Geoffrey F. <fu...@ga...>]

BTW, I reconfigured --enable-dyndrivers, but it still doesn't build:

I haven't had a chance to review the core reasons for the build
failures, but superficially it looks like there's been some changes to
the ldflags make macro, which haven't been completely worked through
in all the cases.  

I can't really drop itcl/itk for my current need, because this is an
itk based app which seeks to embed a plframe (inside a PLXWin).
