Q1. In what order do I compile the libraries?
Q2. What does this error mean?

libcomprex, libpackman, gpkg. The rest of the modules are optional, though libpql will eventually become a requirement. This will be updated at that time.

./configure: line 550: syntax error near unexpected token `AM_INIT_AUTOMAKE($PACKAGE,'
./configure: line 550: `AM_INIT_AUTOMAKE($PACKAGE, $VERSION)'

Try upgrading libtool. If that doesn't work, try upgrading automake or autoconf. The GNUpdate libraries and programs are known to build with automake v1.4-p5, autoconf v2.13, and libtool v1.4. If you still have problems, please contact me.

Try using gettext v0.10.40. The GNUpdate libraries and programs are known to build with gettext v0.10.40 and gettext v0.11.4+. It may not build with v0.11.0 through v0.11.3. Those versions are currently untested.

If you use RedHat v7.3, please upgrade to v0.11.4. If our misc repository is in your apt-rpm sources.list (see Downloads for more information), you will automatically update to this version. Otherwise, please download it here.

Please note that if you are using autoconf v2.50 or higher, you must upgrade gettext to either 0.10.39 or 0.10.40. If you use a lower version, you will receive an error similar to one of the above.
