This i what i got on the PowerPC machine where mklibs failed to operate 
on libslang2

attilio@macswell:~/svn/installer/build$ apt-cache show libslang2-pic 
slang-pic
Package: libslang2-pic
...
Version: 2.0.7-3
Depends: libslang2-dev (= 2.0.7-3)

attilio@macswell:~/svn/installer/build$ dpkg -L libslang2-pic
/.
/usr
/usr/lib
/usr/lib/libslang_pic.a
/usr/share
/usr/share/doc
/usr/share/doc/libslang2-pic
/usr/share/doc/libslang2-pic/copyright
/usr/share/doc/libslang2-pic/changelog.gz
/usr/share/doc/libslang2-pic/changelog.Debian.gz
/usr/share/lintian
/usr/share/lintian/overrides
/usr/share/lintian/overrides/libslang2-pic

as you can see, the /usr/lib/libslang_pic.map file was not provided by 
that version of the package, so i modified the /etc/apt/sources.list 
file to take debs from unstable instead of lenny and, after updating the 
package list, a new libslang2-pic package, version 2.0.7-3 again, was 
pulled in, this time providing the needed map file and i could 
successfully complete the building of the installer.
Still, i wonder why i had to mess with sources.list to get the correct 
package.
Many thanks for helping me solve this issue!
