can't compile libuca on ufo1

Compiling libuca gives the following error:

Have you updated libpco? It looks like you are using an older version which doesn't export pco_set_hotpixel_correction. Unfortunately, I don't have access to ufo1 right now, but can check tomorrow.

P.S.: I'll be more strict regarding version management and bump the version as soon as I change the public API.

[Tomy Rolo]

Thanks for the pointer concerning libpco. However, after compiling it and trying to run the diagnose executable, I get a segmentation fault.

[Tomy Rolo]

BTW, I'm using the most recent revision of these libraries from your personal repository

[Matthias Vogelgesang]

The latest ones should be fine. However, I haven't tested that on ufo1 but will tomorrow.
