Is It Possible To Use The cd Command in chroot?

In a script that I'm still writing, I'm trying to build a package from source within a chroot'ed environment.

1) I could chroot and then cd to /usr/src and then manually install the package.
2) I could chroot and then run the installation script from the proper directory.
3) What I want to do and what's giving me issues, is to issue a command similar to this:

Code:

chroot /root/me/here cd /usr/src

...and have it do the installation after changing to /usr/src.

However, the error that I get is:

Code:

chroot: cannot run command `cd': No such file or directory

I can cd just fine when I manually chroot, but, how can I cd to a directory right from the chroot command option? I can't even find the cd program so that I can hard code the command. (I'm guessing because it's a builtin?) Thanks.

It does not make sense to do that, it wont CD at all. Your better to write a script and execute that script in the chroot instead of going command per command. "cd" is not a real command, it is a built in command of sh/dash/bash/zsh/ksh so you have to lauch bash and telling it to "cd", but it still does not make sense.

Code:

#!/bin/bash
#^^^ Very important here
cd /usr/src
your commands
