The only thing that can tell exactly what happens is the full output
of mklibs with three times the '-v' option ("-v -v -v").
and updated the gzipped logfile [1], but at my inexerienced eyes it
looks like the previous.
No, it now provides the correct info. Here is what seems to happen.
If I call readelf on libslang from unstable on a PPC system, I get:
$ readelf -s libslang.so.2 | grep SLsmg_write_string
319: 000680c0 80 FUNC GLOBAL DEFAULT 11 SLsmg_write_string@@SLANG2
In the log you provided I see:

So it looks like somehow the "@SLANG2" extension changes to "@Base" during
library reduction and that causes that the symbol cannot be found.
Please file a serious BR against mklibs with this info and links to this BR
and the logfile.
2) I have rebuilt some udebs (gtk+, cairo, pango, cdebconf) against
dfb 1.0
Change $debug=0 to 1 in installer/build/util/pkg-list to see what's
pulling it in.
i patched the pkg-list perl script as
That is correct, but your log is incomplete.
You should be getting a lot of output like this near the beginning of the
log (before the line starting with "get-packages"):
