I've compiled ngspice-rework17 for pdaxrom.
As far as I know the only requirement is the readline library (available at the stable
feed).
The package was compiled with xspice support and the included xgraph utility but
without cider support. I removed the example files and some docs in order to make the
package smaller. The most important doc files are in /usr/local/ng-spice-rework/share/docs.
If you want the example files or the complete set of READMEs, download the original source package (ng-spice-rework-17.tar.gz) from
http://ngspice.sourceforge.net/.
The xspice codemodels are included in /usr/local/lib. The "spinit" script (/usr/local/ng-spice-rework/share/scripts) load this codemodel libraries whenever
you run ngspice. You can comment the lines in the script to modify this behavior.
The help files are in /usr/local/ng-spice-rework/share/helpdir so you can use nghelp without problems.
This is the first ipk package I build, so if you have any problem installing, post it here.
I hope you like it
