[Nix-dev] Gnuplot wxt terminal broken

[Peter Simons]

Hi,

when I try to use the wxt terminal in Gnuplot, I get the following error
message:

  $ gnuplot

  gnuplot: symbol lookup error: /nix/store/ggaq9r0ldbi7qik2yrlsm5p8yydgwj9r-pango-1.28.1/lib/libpangocairo-1.0.so.0: undefined symbol: pango_fc_font_create_base_metrics_for_context

Now, the symbol "pango_fc_font_create_base_metrics_for_context" *does* exist,
but it isn't in "libpangocairo", rather it's found in "libpangofc2". 

The Gnuplot source code doesn't seem to contain this function anywhere, so I
reckon that maybe Pango itself has a bug in that regard? Does anyone know
anything about this and/or has an idea how to remedy this problem?

Can others reproduce this problem? Does the wxt terminal work for anyone?

Take care,
Peter
