Perl behavior is to look at env. var. PERL5LIB to find its = library. This should be set to match the Perl that is being invoked, = which is normally done by placing that Perl=E2=80=99s bin directory on = the path. Since I did place it on the path, there are only two = possibilities for why x2go ran /usr/bin/perl: either it hard-coded the = path to Perl, in which case it should first set PERL5LIB (or maybe there = is a Perl command line arg to specify the library folder), OR x2go = ignored my changes to PATH when it ran perl (in which case it should = also ignore PERL5LIB). - Ted > On Jan 10, 2017, at 2:35 PM, Stefan Baur = wrote: >=20 > Control: close -1 > Control: tag -1 not-a-bug >=20 > Am 10.01.2017 um 22:15 schrieb Ted Toal: >> Package: NXAGENT >> Version: 3.5.0 >>=20 >> My .bash_profile defines Perl environment variables for Active Perl, = and adds the Active Perl bin directory to the start of the path.
