Appearently applications using libgps must link -lm themselves. A patch was submitted [1] to change this unusual behaviour upstream, but was never applied. Therefore link to -lm to alfred-gpsd too as this should not hurt anyway.
Hi Simon
What the gpsd sources i have says is:
On some systems (those which do not support implicit linking in libraries) you may need to add -lm to your link line when you link libgps. It is always safe to do this.
So i guess my Debian system does have implicit linking, and ldd on the library does include libm. Hence it worked for me.
However, as you said, it does not harm, so:
