[BioC] problem with get.genes.by.pathway

[Kimpel, Mark William]

I have been working through examples in the new book 

"Bioinformatics and Computational Biology Solutions Using R and Bioconductor"  ISBN:0387251464

The following code chunk leads to an error message. Any ideas on what the problem could be? SessionInfo follows.

library("KEGG")
library("KEGGSOAP")
genes <- get.genes.by.pathway("path:eco00020")

Error in curlPerform(url = url, httpheader = header, postfields = txt,  : 
        Failed writing header

1: get.genes.by.pathway("path:eco00020")
2: unlist(.SOAP(KEGGserver, "get_genes_by_pathway", .soapArgs = list(pathway_id = pathway.id), action = KEGGaction, xmlns = KEGGxmlns))
3: .SOAP(KEGGserver, "get_genes_by_pathway", .soapArgs = list(pathway_id = pathway.id), action = KEGGaction, xmlns = KEGGxmlns)
4: curlPerform(url = url, httpheader = header, postfields = txt, writeFunction = bodyDataFun$update, headerFunction = headerDataFun$update, .opts = .opts)
