Compiling ports on a Wandboard-Quad

Sat Nov 15 11:22:48 UTC 2014

I am trying to compile some TeX related Programs on a wandboard-quad.

root at quad:/usr/src # uname -a
FreeBSD quad 11.0-CURRENT FreeBSD 11.0-CURRENT #1 r274420M: Fri Nov 14
12:57:30 UTC 2014
gwgpi at quad:/usr/local/DEVEL/obj/usr/local/DEVEL/SRC/head/sys/WANDBOARD-QUAD
arm

I have compiled editors/texworks with portmaster.

If I start the program over ssh:

ssh -luser -Y 192.168.0.200

the program starts, but instead of characters I get little black
squares in the window.

I have a screenshot:

Can anybody give me a clue what went wrong?
