i've still been able to do the first section  http://mitpress.mit.edu/sicp/full-text/book/book-Z-H-10.html#%_sec_1.1

i got this when installing with these instructions http://planet.racket-lang.org/package-source/neil/sicp.plt/1/16/planet-docs/sicp/index.html#(part._installation)

i'm not sure if it's soegaard's or neil's or the combination of the packages.

i tried uninstalling by evaluating (uninstall-sicp). but when i installed again, this error did not happen.
