Hi All, Has anyone got a working example tool_dependencies.xml to install the Cairo package into R. (I actually need a package that depends on R Cairo but the current issue is Cairo) I am having the cairo.h not found issue I have cloned https://toolshed.g2.bx.psu.edu/view/devteam/package_cairo_1_12_14/b39299b4b6... (and its dependencies) As well as https://toolshed.g2.bx.psu.edu/view/iuc/package_r_3_1_2/9f2fddb9d6e2 I am trying to use <action type="setup_r_environment"> But can not get the package_cairo to be seen by the R I have tried <action type="set_environment_for_install"> both inside and outside of the setup_r_environment but it does not appear to be working, Full attempted tool_dependencies.xml attached, Thanks in advance Christian University of Manchester
