Can't build WebAssembly on latest version

[zendrael]

Hi!

I keep getting this error every time I try to install webassembly (using the WA button or adding it later):

Warning: Source file "pas2js.pp" from package pas2js not found for x86_64-linux
The installer encountered the following error:
Could not compile target pas2js from package pas2js

fpcupdeluxe: ERROR: Pas2js Installer (BuildModule: pas2js-rtl): make returned error code 512
Details: .

ERROR: Fpcupdeluxe fatal error !
Sequencer (pas2js-rtl): Failure running fpcupdeluxe: error executing sequence pas2js-rtl
Sequencer (Only): Failure running fpcupdeluxe: error executing sequence Only

How to fix this? I'm on Linux x64 and this also happens if I try to add pas2js-rtl only.
