I think I´ll reformat and start over...
I have a SME 5.6 with patch 6 and PHP upgrade from the above link... I don´t know WHAT is going wrong... or why!
I know that I cannot do anymore:pear install Log
It don´t work (read above to see message!)
So I do pear download Log-1.6.7.tgz (as above!)
and pear install Log-1.6.7.tgz ...
and my problems started to happen!
Could you please verify that the howto (and update it if this is the case)still is valid for you (I don´t know if you have a spare machine like me...)
Or just say what Is should to do and I´ll reformat my HDD and start from scratch again!

Thanks by your patience...
