#575 iem_cot~ can't create within vcf_lp2~

[danomatika]

iem_cot~ can't create when instantiating a vcf_lp2~ object from iemlib. I noticed vcf_lp4~ uses iem_cot4~, is this just a typo in the abstraction or is iem_cot~ missing?

I'm on Mac OSX 10.6.4 with pd 0.42.5 RC 4, although I first noticed this problem at least a year ago in 0.41 on Ubuntu Linux ...
