Hi Arun, There is 2 issues in this bug report:
1. the `check' phase is failing but the build ends with "success". 2. a regression of r-rgdal introduced by your commit f9d328833fc1f5d0fb76b61b12d1a3cb013932e6 About the point 1., here is what happens: > --8<---------------cut here---------------start------------->8--- > $ guix build r-rgdal --check --no-grafts -K > [...] > phase `install' succeeded after 19.0 seconds > starting phase `check' > Testing examples for package ‘rgdal’ > /gnu/store/dnb6fzp5295fcda66dnjk2y51mcva20f-r-minimal-3.6.2/lib/R/bin/BATCH: > line 60: 598 Segmentation fault ${R_HOME}/bin/R -f ${in} > ${opts} ${R_BATCH_OPTIONS} > ${out} 2>&1 > [...] > successfully built > /gnu/store/7spmagnk5fycwxsigdypwkmk4kazbw7a-r-rgdal-1.4-8.drv > note: keeping build directory `/tmp/guix-build-r-rgdal-1.4-8.drv-0' > /gnu/store/dgkyzlasbqsxcsfk3n3bgmhrpg447f55-r-rgdal-1.4-8 > --8<---------------cut here---------------end--------------->8--- Therefore, more investigations are required to see why the upstream test suite does not report correctly the failure.

If 'libgeotiff' is really the culprit, then we can try to fix it. All the best, simon
