Thanks! The kernel contains code to detect if a linux program is a script and =20 contains "#!" at the beginning. If it detects this, it tries to start =20 the linux version of the interpreter. At least it should do that. If =20 the above isn't a cut-down version of the ktrace, and if the linux ldd =20 does contain "#!" as the first two characters of the file (I can't =20 check ATM), then there's something wrong here. Regarding the lib problem in the PR: FreeBSD 6.x and fc4 contain a =20 libc.so.6. So the order of the ld path (/compat/linux/etc/ld.so.conf =20 or how it is spelled) may matter. I don't have a 6.x system to test =20 this, so someone has to play around with it and report here (don't =20 forget to rerun the linux ldconfig with the '-R /compat/linux' option =20 after each change). If this doesn't solve the problem, I need to see =20 the complete ktrace of a failing program which tries to link with =20 libc.so.6.
