Legality of creating a build environment

[Creature]

Don't really know if this is in the right forum. I figured since it has to do with an OS and tools, it might as well be put here, but feel free to move it if it doesn't.

I was wondering if it would be legal to create a build environment and put it available for download. The reason why I'm asking this question is because I wanted to incorporate tools like YASM and GCC. I know that I should probably check out the license of these projects (they're both open-source projects), but after knowing their licenses and reading them I'm still not really sure of what I can and can't do.

Would it be legal for me to create some sort of package with YASM and GCC and put it available for download for other developers? Or should I mail the developers asking the same question to them to be sure, has anyone had any experience with something similar?

YASM is licensed under 4 licenses: The BSD License, The LGPL (2.0) license, the GPL (2.0) license and the Artistic License.
GCC is licensed under the GPL (2.0) license.

Thanks for your time,
Creature

This shouldn't be a problem. But don't forget to include the licenses.
You could even sell it.

You could even sell it.

... if you want nobody to use it

Just make sure you include the licenses and (for GPLed stuff) provide a method of downloading the sourcecode.

What I have until now (for YASM) is a directory with the binaries (from the website) and all its licenses in a separate folder. I've also included a readme with a link to the original site and a note about the licenses. So if I do something similar for GCC, it should be enough and it can be uploaded without problems? Does this count for any project under the GPL/LGPL/BSD license?

Thanks .

Yes, Yes. (IANAL)

I've considered doing the same thing with cygwin. Downloading the entire mirror is a *****, so I was going to download it, make a nice installation DVD, and sell it at cost on eBay. But then I couldn't be bothered.
