Unable to create default undionly.kpxe

[The_Immortal]

Hi there!

I'm trying to create undionly.kpxe using this (https://rom-o-matic.eu) service in Standard mode without embedded script and got the error:

Build failed:

"make" unexpectedly returned exit value 2 at /var/www/ipxe-buildweb/build.fcgi line 630

So could you tell me please what's the problem?

Thank you!

P.S. Sorry for formatting... BBCode doesn't work for me - I got [undefined][/undefined] tags for everything.
