xterm (+Konsole) and su on BETA4 with Xorg (from today)

Hello,

attention: perhaps a stupid question, but probably a big problem:

When I su (without -l) I'm not able to build any port. I get the following 
error message (e. g.):


cale:/usr/ports/security/cryptplug# make
===>  Vulnerability check disabled, database not found
===>  Extracting for cryptplug-0.3.16_1

When I su with "-l" it's no problem to build that port. This is _not_ specific 
to cryptoplug at all. Any port fails if I don't "su -l"!

I'm really "stoned". I upgraded from BETA3 to BETA4 (on newfs'd labels, so 
actually it's a reinstall, not a upgrade!) with freshly built ports (KDE3.3, 
formerly KDE3.2.3 but always xorg with nvidia-drivers)

Thanks,

-Mano
