# Before removing the Slackware package, or instead of removing the
# Slackware package, keep a copy of /usr/lib*/libmpc.so.* in case
# something breaks.  If the new version is also symlinked with
# libmpc.so.3 like this one is, you should be fine.  If not, you may
# need to put the older version back in there, or try a symlink:
# ( cd /usr/lib64
#   ln -s libmpc.so libmpc.so.2
#   ldconfig )

# Remove the Slackware package, if there is one
test -x /sbin/removepkg && /sbin/removepkg libmpc

# Install it
make install
ldconfig

# Become yourself again
exit

# Save the source for later
cd
mkdir -p -m 0700 installed
rm -f installed/mpc-*.tar.*
mv -f mpc-1.3.1.tar.gz installed/

# If you ever want to uninstall MPC, this should do it:
cd
