Would linking gmp statically help? E.g. is there a way to link libgmp into the RTS that the symbols are not visible to the linker any more?
It has slightly more licensing complications - GMP is LGPL, which requires that the user of a program that includes it be able to replace GMP. Shared libraries do that easily. Static linking would probably require someone who compiles+distributes a program that uses both Haskell and GMP/MPFR to distribute their .o files (or alternatively their source code), so that they can be re-linked to a different GMP. (Their program still does *not* have to be LGPLed.) The parties I've heard publicly concerned about duplicate packages are Linux/BSD distros that primarily support Free Software. So that complication might not even be a problem (provided the GHC user would get a choice whether to staticly link, and probably default to dynamic linking). ~Isaac
