For LTIB, you can download the nscd source code and then put the source code file (e.g. .tar.gz or .tar.bz2) into /opt/freescale/pkgs/.
Then create a .spec file in the ltib/dist/lfs-5.0/nscd/nscd.spec. (if you don't know how to create this, please take other .spec file for reference.)
After created the .spec file, type the following LTIB commands to build the nscd
./ltib -p nscd.spec -m prep (this command is used to extract the source code into rpm/BUILD/)
./ltib -p nscd.spec -m scbuild (build the source code)
./ltib -p nscd.spec -m scdeploy (install it to rootfs)
