I recently installed R-2.1.1 and R CMD INSTALL gives me the message mkdir: cannot create directory `': No such file or directory before doing whatever it is supposed to do. It looks to me like the script template INSTALL.in has a typo, in line 97: (excerpt follows starting with line 93) startdir=`${GETWD}` : ${TMPDIR=/tmp} { tmpdir=`(mktemp -d -q "${TMPDIR}/R.INSTALL.XXXXXX") 2>/dev/null` \ && test -n "${tmpdir}" && test -d "${tmpdir}" ; } || { test -n "${RANDOM}" && tmp=${TMPDIR}/R.INSTALL$$-${RANDOM} \ && (${MKDIR_P} "${tmpdir}") ; } || { tmpdir=${TMPDIR}/R.INSTALL.$$ && (${MKDIR_P} "${tmpdir}") ; } || (error "cannot create temporary directory" && exit 1) tmpdir=`cd "${tmpdir}" && ${GETWD}` where the "tmp=" midway through should I think be "tmpdir=". Making that change solved the problem. I didn't see the problem mentioned anywhere so thought I should point it out and make sure I'm not breaking something. Reid Huntsinger
