In general, binary distributions of the LDM package are not supported; consequently, you must build and install the package from the source distribution.
Other reasons why it is better to use the source-distribution include the following:
You are sure to get the most recent version of the package (besides being unavailable, any binary version will never be more recent than the source-code version and can be significantly older);
You can support product-queues larger than 2 gigabytes;
The pathname of your perl 5 utility is not /opt/bin/perl;
You can modify the LDM programs;
You can write your own LDM-compatible programs;
You can port the LDM to a non-supported platform;
You can use a non-standard installation setup;
You can look at the code (in order to fully understand an error-message, for example);
You can gripe about the developer being an idiot!
Building the LDM package from source should add only a few minutes to the total installation time.
