I have problem, I reinstall my Ubuntu to latest version 12.04, I also get 64bit version. Then I install wine like usual bat some programs doesn't work and I always get the same error :
p11-kit: couldn't load module: /usr/lib/i386-linux-gnu/pkcs11/gnome-keyring-pkcs11.so: /usr/lib/i386-linux-gnu/pkcs11/gnome-keyring-pkcs11.so: sdílený objektový soubor nelze otevřít: Adresář nebo soubor neexistuje
I'm also running 64-bit Ubuntu 12.04 and have installed Wine 1.5.8 binaries. When I run winecfg I get the same message due to the missing pkcs11 directory.
Otherwise, my VB6 application generally runs fine... except for intermittent page fault errors when I run the OpenGL graphics part of my application.
