[Pkg-electronics-devel] Bug#1108620: ngspice: Prospective upgrade of blt to 3.0 affects ngspice

[Carsten Schoenert]

I haven't heard from upstream about a new planned version for NGspice 
yet but let's forward your news to Holger Vogt from the NGspice team.
You changes will also affect Ubuntu at one day.
