[BioC] Error installing impute package

[Peter Langfelder]

Hello,

a user of my (CRAN) package WGCNA which depends on impute has a
problem installing impute on his Mac OSX 10.8.3 under R 3.0.0. The
problem seems to be loading the compiled libary impute.so. Can anyone
please suggest a solution? Below is a transcript of his session.

Thanks,

Peter
