Okay, I set up one of those pbuilder thingies (amd64, unstable), tried
to build r-base, and it failed at the same place the mipsel buildd failed:
make[5]: Leaving directory `/tmp/buildd/r-base-2.10.1/src/library/tools'
Error in read.dcf(file = descfile) : Line starting 'P ...' is malformed!

E: Failed autobuilding of package

subdirectories
Does that help any? To my untrained eye, the problem seems the same
whether one is trying to do pbuilder or apt-get source -b .

And I am getting

Error in read.dcf(system.file("DESCRIPTION", package = "lattice"),
"Package") :
Line starting 'P ...' is malformed!

goodr...@x41laptop:/tmp$ r -p -e'read.dcf(system.file("DESCRIPTION",
package="lattice"), "Package")'
Error in read.dcf(system.file("DESCRIPTION", package = "lattice"),
"Package") :
Line starting 'P ...' is malformed!
That error message comes from the C function do_readDCF when it falls into
else {
/* Must be a regular line with no tag ... */
line[20] = '\0';
error(_("Line starting '%s ...' is malformed!"), line);
So, due to some dependency that changed at approximately Christmas, it
does not parse a line in a DESCRIPTION file like
Package: lattice
as having the Package tag, but the problem may be higher up in that
function. I tried adding some more print statements in do_readDCF to see
what was happening but this error prevents me from building r-base-core
from source and I am not hitting the error when using the CRAN source.
Thanks,
Ben
