But that is generated by configure, which does

configure:for ac_prog in ${PAGER} less more page pg

so if it ends up with "more" as the default, I'd say that the test for "less" failed in the build environment. Either that or the shell itself sets PAGER to "more". 

(Conversely, you can always override it by "export PAGER=less" before starting R, or Sys.setenv(PAGER="less"), etc.)
