fUnitRoots failing with urca import due to BIC

[Dirk Eddelbuettel]

Hi all,

During a routine rebuild of the Debian archive, it was noticed that
fUnitRoots no longer builds (http://bugs.debian.org/628324):

make[1]: Entering directory `/tmp/buildd/funitroots-2100.76/src'

Did something change in nlme which upsets urca?  I only see (in urca's
NAMESPACE)

## Import functions

importFrom(graphics, plot)

if (!exists("BIC", envir=asNamespace("stats"))) {
    importFrom(nlme, BIC)
} else {
    importFrom(stats, BIC) # unless you already import stats
}

I tried adding 'stats' to the Depends: in urca's DESCRIPTION but not beans. 

Any ideas?
