This is almost like bug #272254 and #332317, but supposedly enabling the extension still causes the same error: stuartl@vk4msl-ws ~/vrt/projects/widesky/niagara/nhaystack $ cat ~/.hgrc # example user config (see 'hg help config' for more info) [ui] # name and email, e.g. # username = Jane Doe <jdoe@example.com> username = Stuart Longland <stuartl@vrt.com.au> # uncomment to disable color in command output # (see 'hg help color' for details) # color = never # uncomment to disable command output pagination # (see 'hg help pager' for details) # paginate = never [extensions] hgext.hgk = stuartl@vk4msl-ws ~/vrt/projects/widesky/niagara/nhaystack $ hgk Error in startup script: no such variable (read trace on "env(HG)") invoked from within "exec $env(HG) debugconfig" (procedure "getconfig" line 5) invoked from within "getconfig" invoked from within "array set config [getconfig]" (file "/usr/bin/hgk" line 4148) I've also tried removing the space before the equals, to no effect. Interestingly, if I run `hg help extensions` I see: enabled extensions: hgk browse the repository in a graphical way which implies it is in fact enabled. `emerge --info`: stuartl@vk4msl-ws ~ $ emerge
