Dear Frank, dear Norbert, dear UCF maintainers! Recently, I found the error. It was a setting in my environment, namely in the variable GREP_OPTIONS. In GREP_OPTIONS, among others, I also included the flag '-n' to give line numbers in the output. Some script of one of the packages seems to call grep, but does not expect line numbers in the form "NUMBER:" at the beginning of each line in the output. These numbers, however, then entered the files /var/lib/ucf/registry*. And then the error occured .....
Since this setting of GREP_OPTIONS caused a lot of further errors, meanwhile, I erased the setting from all of my .bashrc files. E.g. it prevented me from compiling some Mozilla software (Firefox and Thunderbird) as well as kernel modules. I could compile an ALL-YES kernel, but no *.ko file would have been created resulting in the message Building modules, stage 2. MODPOST 0 modules Apart from vanilla kernel modules this problem also occured for third-party modules as e.g. the NVIDIA graphics driver. Curiously, I couldn't find any hint on this matter in the internet. That's why I mentioned the Mozilla and Kernel problems as well. Maybe, that can be of help to someone .... So, the problem is solved. You may close this bug report. Sorry for bothering you and thanks for your help.
