Hi this is a problem that occured on freebsd5.x as well. Box running
6.0-release.
after a configure as a non root user and typing make I get permission denie=
d.
ezbounce-1.50-pre8 # make
make: Permission denied
ezbounce-1.50-pre8 # which make
/usr/bin/make
ezbounce-1.50-pre8 # ls -l /usr/bin/make
-r-xr-xr-x 1 root wheel 284812 Mar 17 06:38 /usr/bin/make
and then doing this it will work
ezbounce-1.50-pre8 # cd ..
chrysalis # cd ezbounce-1.50-pre8
ezbounce-1.50-pre8 # make
cd src; make all
cd ../lib/ ; make all
g++ -D__EZBOUNCE__ -Wall -O2 -c dynbuff.cpp
.......
after speaking to someone else they also pointed out simply doing a cd
. makes it work also.
here is some strace outputs
strace from failure.

So the cwd is where it starts going wrong, I assume the configure cd's
to somewhere it doesnt like and it makes it go bad, when I added cd .
to the end of the configure script it works.
Some other info.
This happens with a lot of source apps, eggdrop, psybnc, ultimateircd etc.
It only happens as non root users.
It seems to only happen right after running configure, so if I do
anything like cd . or logout and relogin as the user there is no
problem. So to reoccur the problem run ./configure then make and bam
the access denied, simply typing make again will give same error but
then do anything else that requires a dir traversal it works.
this happened in freebsd 5.x as well but I believe it doesnt occur in
freebsd 4.x.
It is a nuisance because if I supply user accounts for shells user's
will tend to upgrade src tarballs and the compile their own stuff and
will hit this problem.
I dont know if it is a bug with make or not but I would like to know
what makes it break, let me know if you need more info, thanks.
