Currently, sci-geosciences/gpsbabel-1.5.4 has an optional dependency on Qt 5 (with unspecified minor version), if USE="qt5" is specified. However, trying to build the package without Qt 5 installed results in this build error: >>> Compiling source in /var/tmp/portage/sci-geosciences/gpsbabel-1.5.4/work/gpsbabel-1.5.4 ... make -j4 x86_64-pc-linux-gnu-g++ -march=native -O2 -pipe -fweb -ftracer -std=gnu++11 -Wall -c -I. -I/usr/include/qt4 -DHAVE_CONFIG_H -DNEW_STRINGS main.cc -o main.o x86_64-pc-linux-gnu-g++ -march=native -O2 -pipe -fweb -ftracer -std=gnu++11 -Wall -c -I. -I/usr/include/qt4 -DHAVE_CONFIG_H -DNEW_STRINGS globals.cc -o globals.o x86_64-pc-linux-gnu-g++ -march=native -O2 -pipe -fweb -ftracer -std=gnu++11 -Wall -c -I. -I/usr/include/qt4 -DHAVE_CONFIG_H -DNEW_STRINGS queue.cc -o queue.o x86_64-pc-linux-gnu-g++ -march=native -O2 -pipe -fweb -ftracer -std=gnu++11 -Wall -c -I. -I/usr/include/qt4 -DHAVE_CONFIG_H -DNEW_STRINGS route.cc -o route.o x86_64-pc-linux-gnu-g++ -march=native -O2 -pipe -fweb -ftracer -std=gnu++11 -Wall -c -I. -I/usr/include/qt4 -DHAVE_CONFIG_H -DNEW_STRINGS waypt.cc -o waypt.o main.cc:256:4: error: #error This version of Qt is not supported. #error This version of Qt is not supported. ^ x86_64-pc-linux-gnu-g++ -march=native -O2 -pipe -fweb -ftracer -std=gnu++11 -Wall -c -I. -I/usr/include/qt4 -DHAVE_CONFIG_H -DNEW_STRINGS filter_vecs.cc -o filter_vecs.o make: *** [Makefile:121: main.o] Error 1 make: *** Waiting for unfinished jobs....

================================================================= sci-geosciences/gpsbabel-1.4.4::gentoo was built with the following: USE="-doc qt4" ABI_X86="64"
Oldest Qt5 version in tree is 5.6.1 so we are fine, raising the version dep would awnot change anything. But indeed what an oversight, I'll drop USE=qt5 from the ebuild as it is not really supported. Thanks, fixed in git by commit 4253275cb926d196b7a3566ff28a8cf756ae8138.
