Has anyone looked at setting up R to build its modules with libtool's dlpreopen?
[libtool -dlpreopen is a facility that allows one to simulate dynamic linking on platforms that lack it.
No current R platform does.
The static linking workarounds are for a Cray MTA/2, a multithreaded supercomputer. Although having a rather primitive runtime environment (e.g. no dynamic linker), it does have an advanced parallelizing compiler. (The practical usage is kind of fly-by-wire setup using a front-end workstation.) The MTA/2 is fast architecture for memory-intensive applications.
