Apt-get :: dpkg and libc6

Hi all
dunno if this is the right place to post it, so please don't blame me

i got a dsl-n
i had gcc1-with-libs and gcc-2.95 on my mydsl folder (to be loaded and installed at startup. btw i sometime get it into mydsl/optional so are not loaded at startup) both installed from .dsl or .unc package (don't remember)
i got also dpkg to install .deb package (i need some package not present in dsl repositories)
i got also libc6

and dpkg -l show this

Code Sample

# dpkg -l    Name           Version +++-==============-============== ii  linux-kernel-headers 2.5.999-test7-bk-17 ii  libc6-dev      2.3.2.ds1-22sarge5 ii  libccid        0.9.3-1 ii  libpcsclite1   1.2.9-beta7-5 ii  xfstt          1.2.1-3

and

Code Sample

# ls /UNIONFS/lib/ | grep libc libc-2.3.2.so libc.so.6 libcap.so.1 libcap.so.1.10 libcfont.so.0 libcfont.so.0.0.0 libcom_err.so.2 libcom_err.so.2.1 libconsole.so.0 libconsole.so.0.0.0 libcrypt-2.3.2.so libcrypt.so.1 libctutils.so.0 libctutils.so.0.0.0

then i sometime try to install .deb package, and i got a lot of problem. recurring problem is "libc6 is not present in your system".
BUT
i'm pretty sure IT IS, both from dpkg -l info and 'cause is in /lib folder (and also 'cause i use some libc6 requiring apps -_- )
btw i tried also install libc6, dowloaded from debian homesites, and it says it requires libc6!!

sometime i can install it using "-F depends" but sometimes i can't

now, i'm installing xfstt (to install new fonts like i read in http://damnsmalllinux.org/f/topic-3-26-18569-0.html ) and it seems installing fine BUT whenever i try to run xfstt i get error while loading shared libraries: libstdc++-libc6.2-2.so.3
googling and forum-searching i found http://www.damnsmalllinux.org/dsl-n/f/viewtopic/90.html where it says to install libstdc++2.10-glibc2.2_2.95.4-22_i386.deb
BUT
it says again it requires libc6 >_>
what's wrong?

thanks for help and forgive me if i'm always asking for help... i'm still a noob

ty for help
