The blender download is a binary blob. For a longer time I used to
build blender myself from a daily snapshot of the repository, but
this became more and more complicate and finally I gave up.
I started to download the binaries directly from the build bot
builder.blender.org.
This works - until now.
The error stops the start of blender.
ldd gives "libprce.so.3 not found" (see above) indicating, that
blender won't start at all.
The binary blob does not contain any libpcre -- I checked that
before.
Well, I think I have to open a bugreport for Ton...
Anyway: Thanks for your help, Alan!
Best regards
Meino
