[plt-scheme] upgrading to 200 from 103

[Deva Seetharam <deva@media.mit.edu>]

hi all,
last night, i posted a message about problems with defining macros in v103.
many of you suggested that i should upgrade to 200.

i tried 200 and i encountered some problems while importing libraries.
i have a bunch of files and each of them import libraries. when i load
these scm files in the mzscheme, if a same file is imported twice (from
2 different code files), mzscheme gives an error message that the lib is
not found (i dont rememeber the exact msg text). 

also, since it is v200 is still not stable, i didnt want to be wrestling 
with such unknown problems.

or, is v200 quite safe to use?

thanks,
Deva Seetharam
