Bug#815373: r-cran-tm: FTBFS: dependencies 'NLP', 'slam' are not available

[Aaron M. Ucko]

Source: r-cran-tm
Version: 0.6.2-1
Severity: serious
Justification: fails to build from source

Hi, Daniel.

Builds of r-cran-tm in minimal environments (notably, on the
autobuilders) have been failing:

  ERROR: dependencies 'NLP', 'slam' are not available for package 'tm'
  * removing '/«PKGBUILDDIR»/debian/r-cran-tm/usr/lib/R/site-library/tm'
  /usr/share/R/debian/r-cran.mk:98: recipe for target 'R_any_arch' failed
  make: *** [R_any_arch] Error 1

Please declare build dependencies on r-cran-nlp and r-cran-slam, and
confirm with pbuilder or the like that you haven't missed any others.

Thanks!
