AFAIU Raudus is closed source, and usable only with the .ppu files
distributed with the package (of whatever version). This means it is
100% sensitive to the slightest change in compiler version. Since (in
theory) a new FPC version is produced with each nightly build it could
take only one day for your Raudus package to be incompatible with a
newer FPC.
Read the docs that come with Raudus and note the exact FPC version it
requires. Deviate from that in the slightest and you will not be able
to compile or install the package.

howardpc is right. Indeed there was a problem while installing Raudus
for Lazarus. Raudus required exact Lazarus version. Moreover, if you
rebuild Lazarus, Raudus became incompatible with your Lazarus (you got
"wrong checksum" and "can not find RaCreatorFPC" errors).

But the problem is solved. New utility "welding" is introduced. The
utility scans and parses Raudus PPUs and Lazarus PPUs, patches Raudus
PPUs, and rebinds Raudus foreign links to Lazarus declarations. Of
course, it patches checksum bytes in Raudus PPUs to make them equal to
Lazarus checksums.

Hence, the only restriction to use Raudus is FreePascal 2.6.2 (fixed
at PPU version 135). Raudus supports any Lazarus deviation - you can
make Raudus compatible with any Lazarus build (including dev snapshot)
- just run "welding".

I downloaded and installed Raudus, but there is no welding utility
anywhere. I repeated the process in case there have been any
installation error, but no cigar. Where can I found the utility?

Welding is placed among PPU files - probably c:\Program
Files\Raudus\bin\fpc262\i386-win32\welding.exe
