[Bioc-devel] library(Biostrings) gives me an error

Dear list,

I am facing the following error and google is quite quiet to help me.\

Has anyone seen it before ?
Note that I have the dependencies list on the website installed (I can
send my library() is needed).

Thanks for your help,

Best regards,

Pierre
