Install portmap with the following commands:
patch -Np1 -i ../portmap-5beta-compilation-fixes-2.patch && patch -Np1 -i ../portmap-5beta-glibc-errno-fix.patch && make && make install |
Note: The above installation places executable portmap in /sbin. You may choose to move the file to /usr/sbin. If you do, remember to modify the bootscript.

portmap is the RPC port mapper.
pmap_dump saves the port mapping table to an ASCII file.
pmap_set restores the port mapping table from an ASCII file.
