NPE in PrismFontLoader.java: Loading primary font factory failed

[Kevin Rushforth]

What I meant was for you to find out whether the system pango library 
that javafx_font_pango.so depends upon is present. Run the "ldd" 
commands and make sure there are no missing dependencies.

Also, I hadn't noticed you were trying to use the ARM bits. Maybe Dave 
Hill has some additional thoughts on this.
