Dear Matthias, I'd like to inform you that we've just had a successful installation of ALPS 2 beta 3 on AIX after turning off examples. At the moment the build of applications is turned off, since I needed a very basic configuration for compiling my code. We're going to try soon with build applications on and I'll let you know if there are any issues again. Then we'll try more recent revisions of ALPS. Thank you very much again for your support. Best regards Jessica
