#147 'plplot_config.h' file not found
I'm trying to install 3rd party software (GDL) that relies on plplot. I have plplot 5.10.0 installed on OS X from HomeBrew, and 5.9.11 tarball and latest svn.
GDL reports,

There is no plplot_config.h that I can find. It seems like there has been a similar bug report a few weeks ago from macports/Octave users here: https://trac.macports.org/ticket/43985
plplot_config.h is not installed for the reasons given in that file and also in plConfig.h. Furthermore, it appears to me your build is looking for that file because you have incorrectly #defined the PLPLOT_HAVE_CONFIG_H macro for your builds against PLplot. My guess is that dropping that macro definition in your builds should completely solve this issue. Please let me know the results of that experiment, and we can take it from there.
Perhaps this should be closed. GDL devs pointed out this bug fixed in April.

Unfortunately April was after latest release... So I'm now waiting for next release, and the propagation through the Homebrew package system.
Thanks for those references which reminded me that the source of this issue was that released versions of PLplot used the HAVE_CONFIG_H macro which nameclashed with other software causing the issue you have described. That nameclash has been fixed in the latest PLplot svn trunk version, but it will be a while (at least several months) before that will be released. Meanwhile, I am closing this bug and also suggest you build your own version of PLplot from svn trunk if you don't want to wait for the release of PLplot 5.11.0 and its propagation through Homebrew.
