Alex,

As far as I can see this should have worked, and I'm quite mystified
at the error you got since the proj.4 string does contain +ellps=airy
defining the ellipse.

ERROR 6: Failed to initialize PROJ.4 with `+proj=tmerc +lat_0=49 +lon_0=-2 
+k=0.9996012717 +x_0=400000 +y_0=-100000 +ellps=airy +datum=OSGB36 +units=m 
+no_defs'

I'm sorry I can't offer any sort of useful suggestion.

Best regards,
