Tried to compile pix_opencv against Gem git. Loading Gem and then
pix_opencv threw a similar albeit not identical error:

src/pix_opencv/pix_opencv.l_ia64: src/pix_opencv/pix_opencv.l_ia64:
undefined symbol: _ZN7GemBase14beforeDeletionEv
translated using 
	c++filt _ZN7GemBase14beforeDeletionEv
to
	GemBase::beforeDeletion()

The last time when I compiled against gem 0.93.3 from Debian testing
package the error was
	GemPixObj::SIMD(int)


Antoine mentions that he is able to load pix_opencv installed from
Deken.
Is anyone else able to compile/load pix_opencv with Gem 0.93.3 on 64bit
Debian testing?
Any help is very welcome! It would be sad having to abandon pix_opencv
due to these errors.

Thanks!
