Hi i do a upgrade to 6.0 STABLE without problems but checking the /lib
folder i found this.

libalias.so.4      libcam.so.3        libipsec.so.1      libncurses.so.6
libalias.so.5      libcrypt.so.2      libipsec.so.2
libreadline.so.5
libatm.so.2        libcrypt.so.3      libipx.so.2
libreadline.so.6
libatm.so.3        libcrypto.so.3     libipx.so.3        libsbuf.so.2
libbegemot.so.1    libcrypto.so.4     libkiconv.so.1     libsbuf.so.3
libbegemot.so.2    libdevstat.so.4    libkiconv.so.2     libufs.so.2
libbsdxml.so.1     libdevstat.so.5    libkvm.so.2        libufs.so.3
libbsdxml.so.2     libedit.so.4       libkvm.so.3        libutil.so.4
libbsnmp.so.2      libedit.so.5       libm.so.3          libutil.so.5
libbsnmp.so.3      libgeom.so.2       libm.so.4          libz.so.2
libc.so.5          libgeom.so.3       libmd.so.2         libz.so.3
libc.so.6          libgpib.so.0       libmd.so.3
libcam.so.2        libgpib.so.1       libncurses.so.5

i have two versions of the same libraries , i think that the upgrade
procces deleted allthe obsoleted libraries but not in my case :-(
what can i do..
