I've upgraded my GCC to 4.3.2 (from the Gentoo portage tree) and set it to be my default system compiler. Today after emerge --sync and emerge -uD world, this happened while trying to compile vsftpd: i686-pc-linux-gnu-gcc -c sysdeputil.c -O2 -march=i686 -pipe -idirafter dummyinc sysdeputil.c:520: error: conflicting types for 'capset' sysdeputil.c:166: error: previous definition of 'capset' was here make: *** [sysdeputil.o] Error 1 * * ERROR: net-ftp/vsftpd-2.1.0 failed. * Call stack: * ebuild.sh, line 49: Called src_compile * environment, line 2139: Called die * The specific snippet of code: * emake CFLAGS="${CFLAGS}" CC="$(tc-getCC)" || die * The die message: * (no error message) * * If you need support, post the topmost build error, and the call stack if relevant. * A complete build log is located at '/var/tmp/portage/net-ftp/vsftpd-2.1.0/temp/build.log'. * The ebuild environment file is located at '/var/tmp/portage/net-ftp/vsftpd-2.1.0/temp/environment'. * Compiling vsftpd works with the previous Gentoo version of GCC (I think it was 4.1). Reproducible: Always Steps to Reproduce: 1. Set your system default compiler to gcc 4.3.2 (gcc-config i686-pc-linux-gnu-4.3.2). 2. Do an emerge --sync. 3. Do an emerge vsftpd.

It does not look like a gcc 4.3 failure. More info, please: - output of 'emerge -1pv net-ftp/vsftpd' - output of 'equery l libcap'

Indeed, you were right - it is not a GCC version issue. I just emerged libcap, and this has brought in sys-libs/libcap-2.16. After that, vsftpd did compile and install. However, if that is a required dependency, I assumed that emerge -uD world would have taken care of that...
It seems, that the patch that makes it an optional dep is not quite correct. But it's in maintainer-needed, so it's not that surprising.
Created attachment 192846 [details, diff] Update of existing vsftp-2.1.0 patch for vsftp-2.1.1 FYI, I've attached an updated version of the existing "vsftpd-2.1.0-dont-link-caps.patch" that works with vsftpd-2.1.1.
Since libcap-1 is gone from the tree, i've forced the depend on libcap-2.
