[BioC] KEGGgraph: retrieveKGML error (due to wrong ftp path)

[Ludwig Geistlinger]

Dear BioC developers,

as I try to use the retrieveKGML function of the KEGGgraph package, I end up with the following error:

------

retrieveKGML(pathwayid='00010', organism='cel', destfile="/home/cbio/ludwig/test.txt", method="wget")
--17:06:46--  ftp://ftp.genome.jp/pub/kegg/xml/organisms/cel/cel00010.xml
           => `/home/cbio/ludwig/test.txt'
Resolving ftp.genome.jp... 133.103.100.184
Connecting to ftp.genome.jp|133.103.100.184|:21... connected.

==> SYST ... done.    ==> PWD ... done.
==> TYPE I ... done.  ==> CWD /pub/kegg/xml/organisms/cel ... 
No such directory `pub/kegg/xml/organisms/cel'.

Warning message:
In download.file(kgml, destfile = destfile, method = method, ...) :
  download had nonzero exit status

------

This might be due to a wrong hard coded kegg ftp path inside of KEGGgraph, as the recent integration of biopax files has changed the structure of the ftp://ftp.genome.jp/pub/kegg/xml/ directory.
This has destroyed the nice functionality of retrieveKGML.
