Dear R People: I'm trying to install spsurvey and rgeos in R-2.15.1 on Ubuntu 12.04. However, I am getting the following: * installing *source* package ?rgeos? ... ** package ?rgeos? successfully unpacked and MD5 sums checked checking geos-config usability... ./configure: line 1342: geos-config: command not found no configure: error: geos-config not usable ERROR: configuration failed for package ?rgeos? * removing ?/home/erin/R/x86_64-pc-linux-gnu-library/2.15/rgeos? ERROR: dependencies ?deldir?, ?rgeos? are not available for package ?spsurvey? * removing ?/home/erin/R/x86_64-pc-linux-gnu-library/2.15/spsurvey? Do these look familiar please?
