Hello,

thanks for the hint, I think a lib is missing.

Indeed I have something installed that is named lrexlib-pcre, but Arch Linux 
does not
come with an official package, so it is maybe packaged incorrectly. I will try 
to dig
into this.

Other problem could be a race condidtion. The output of make-d seems to suggest 
this.

Thanks also for the hint to the verbose run of make, I did not know about this.
