[Bioc-devel] [R-pkg-devel] DESCRIPTION file building problem

Hi,

I've a package with a DESCRIPTION file inside of it, as usual.

It's a couple of times that, when I try to build the package on my local 
machine or on travis-ci, I get this error:

Building package
Building with: R CMD build
0.74s$ R CMD build .
* checking for file ?./DESCRIPTION? ... OK
* preparing ?mypackage?:
* checking DESCRIPTION meta-information ...OK
* cleaning src
Error in .read_description(ldpath) :
file 'mypackage/DESCRIPTION' does not exist
Execution halted

Someone knows what does it depends on?

Thanks,
dario
