I'm OK with sourcing the script before running the program (even though it would be ideal if location of data file could be remembered and only overloaded when the corresponding environmental variable is set; that way I could easily run the binary without any extra variables), but I still wonder why default behaviour of the script is to set DYLD_LIBRARY_PATH which more or less "makes the whole system useless". Once I set that variable, I'm unable to run any given program from the shell.
I'm aware that the functionality on Linux differs a lot, but I'm curious if there are some circumstances that make setting DYLD_LIBRARY_PATH on Mac OS X necessary/unavoidable.
Thank you, Mojca
