Versions 2.5.0 and 2.5.1 currently fail "make check" on my system due to a
silent failure in the call to Rd_db("base"):

Error in as.vector(x, mode) : invalid argument 'mode'

Tracing through the call to Rd_db, a call is made to list_files_with_exts(). The
functionality of the relevant section of that function in 2.4.0 is replicated
here:
> dir
[1] "/usr/local/packages/R-2.4.0-acml/lib64/R/library/base/man"
> files <- list.files(dir)
> files
[1] "base.Rd.gz"
> patt
[1] "\\.(Rd|rd|Rd.gz|rd.gz)$"
> grep(patt, files, value = TRUE)
[1] "base.Rd.gz"
In 2.5.1, the behaviour of grep() seems to have changed:
> dir
[1] "/usr/local/packages/src/R-2.5.1/library/base/man"
> files <- list.files(dir)
> files
[1] "base.Rd.gz"
> patt
[1] "\\.(Rd|rd|Rd.gz|rd.gz)$"
> grep(patt, files, value = TRUE)
character(0)
The result is that the call to Rd_db fails to find the relevant documentation
for the base package.
