Fpclazup failed.
Please check log for details. Possible troubleshooting steps:
First action :
Run fpcup again with --verbose and check for make, lazbuild errors etc.
Run fpcup again also in case of incomple download due to SVN errors.

If that does not work ... last resort action :
Remove all files from install-directory, and try again

2.6.5 doesn't have a REQUIRED_VERSION in it's Makefile.fpc.

[LongDirtyAnimAlf]

Confirmed. Will look into it.

Will be fixed in next release: 1.6.1b Fix already in source and tested.
