I agree it seems unlikely that the size difference is due to 64 bit versus 32 bit. To confuse issues some more, the size of the older system version of libQtGui on my 64-bit system is -rw-r--r-- 1 root root 9.4M 2008-09-29 16:23 /usr/lib/libQtGui.so.4.4.3 I wonder if this factor of 10 size difference between the two 64-bit versions on my machine is due to the system one being stripped and the downloaded one not being stripped? Anyhow, the basic point still remains that the required Qt libraries are not small under all circumstances. If it is something as simple as stripping, that still adds an additional headache (finding Qt libraries to distribute that are stripped). Getting into the _complete_ binary distribution business is hard for something like PLplot with all its dependencies. Hazen, I would advise avoiding all that pain by sticking with just distributing a binary version of PLplot without the external dependencies. That is hard enough already because I just realized you are going to have to think carefully about the 64-bit versus 32-bit issue. I notice, for example, that on the Qt binary download page there are 64-bit and 32 bit Linux versions but no such separation for Mac OS X and Windows. It's quite possible that means those OS's deal with 32-bit versus 64-bit automagically. OTOH, there may be an assumption or de facto standard that all binary distributions for those OS's are 32-bit. I don't know. BTW, I think there has been an attempt by some Linux distributions to support mixed 32-bit and 64-bit systems. I don't know whether that effort is continuing, but I am very happy with my pure 64-bit system for Debian, and I wouldn't want the heachaces of mixing in some 32-bit apps and libraries.
