Hi, I had the same problem (btw. very annoying problem). After analisys of this #$%^&*!!! and test ALL posibilities checked in magic sub "find_perl_interpretter" to find /usr/bin/perl I decided to insert 1 simple line at the begining of this sub:
After then I just ignore funny warning "* WARNING: Configuration was initially created with '/usr/bin/perl', but we are now using '/usr/bin/perl'." because of its stupidity. Works wonderfully.
