Hello,

I'm relatively new to bioconductor development, and I've a problem with an error R CMD check spits out:

R CMD check Gviz

BiocInstaller version 1.3.7, ?biocLite for help

Loading log:
Loading required package: grid
Error in loadNamespace(i[[1L]], c(lib.loc, .libPaths())) :
  there is no package called ‘Biobase’
Error: package/namespace load failed for ‘Gviz’
Execution halted

I can build and install the Gviz package as well as loading it in an interactive R-session (and grid and Biobase, too). Any idea how to figure out where the problem is?

 Thanks a lot for your help,

 Arne
