in reply to Problem installing Wx::TreeListCtrl (solved!)

Interesting...
I had Wx installed via apt-get, at least I thought so, as I remembered it to fail via cpan. Then running "sudo cpan -i Wx" again, ran through and compiled fine.
Doing "cpan -i Wx::TreeListCtrl" then, succeeded as well:
Writing 'cpp/ovl_const.h'. Writing 'cpp/ovl_const.cpp'. Checking if your kit is complete... Looks good 'WX' is not a known MakeMaker parameter name. Unrecognized argument in LIBS ignored: '-Wl,-Bsymbolic-functions' Unrecognized argument in LIBS ignored: '-Wl,-z,relro' Writing Makefile for Wx::TreeListCtrl Writing MYMETA.yml and MYMETA.json cp lib/Wx/TreeListCtrl.pm blib/lib/Wx/TreeListCtr ...
So, as it seems, the system simply was lacking Wx....

*facepalm*
