I was running libtool-1.5.26, could not emerge gobject-introspection, but could after upgrading libtool to 2.2.4. The errors were things like /bin/sh ../libtool --tag=CC --mode=compile i686-pc-linux-gnu-gcc -DHAVE_CONFIG_H -I. -I.. -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -fno-strict-aliasing -Wsign-compare -Wcast-align -Wpointer-arith -Wnested-externs -Wmissing-prototypes -Wmissing-declarations -Wchar-subscripts -Wall -O2 -march=pentium4 -pipe -fomit-frame-pointer -MT libgirepository_1_0_la-girepository.lo -MD -MP -MF .deps/libgirepository_1_0_la-girepository.Tpo -c -o libgirepository_1_0_la-girepository.lo `test -f 'girepository.c' || echo './'`girepository.c /bin/sh ../libtool --tag=CC --mode=compile i686-pc-linux-gnu-gcc -DHAVE_CONFIG_H -I. -I.. -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -fno-strict-aliasing -Wsign-compare -Wcast-align -Wpointer-arith -Wnested-externs -Wmissing-prototypes -Wmissing-declarations -Wchar-subscripts -Wall -O2 -march=pentium4 -pipe -fomit-frame-pointer -MT libgirepository_1_0_la-gtypelib.lo -MD -MP -MF .deps/libgirepository_1_0_la-gtypelib.Tpo -c -o libgirepository_1_0_la-gtypelib.lo `test -f 'gtypelib.c' || echo './'`gtypelib.c ../libtool: line 838: X--tag=CC: command not found ../libtool: line 838: X--tag=CC: command not found ../libtool: line 871: libtool: ignoring unknown tag : command not found ../libtool: line 838: X--mode=compile: command not found ../libtool: line 871: libtool: ignoring unknown tag : command not found ../libtool: line 838: X--mode=compile: command not found ../libtool: line 1005: *** Warning: inferring the mode of operation is deprecated.: command not found ../libtool: line 1006: *** Future versions of Libtool will require --mode=MODE be specified.: command not found ../libtool: line 1149: Xi686-pc-linux-gnu-gcc: command not found ../libtool: line 1149: X-DHAVE_CONFIG_H: command not found ../libtool: line 1149: X-I.: command not found ../libtool: line 1149: X-I..: command not found ../libtool: line 1149: X-I/usr/include/glib-2.0: No such file or directory ../libtool: line 1149: X-I/usr/lib/glib-2.0/include: No such file or directory ../libtool: line 1149: X-fno-strict-aliasing: command not found ../libtool: line 1149: X-Wsign-compare: command not found ../libtool: line 1149: X-Wcast-align: command not found ../libtool: line 1149: X-Wpointer-arith: command not found ../libtool: line 1005: *** Warning: inferring the mode of operation is deprecated.: command not found ../libtool: line 1149: X-Wnested-externs: command not found ../libtool: line 1006: *** Future versions of Libtool will require --mode=MODE be specified.: command not found ../libtool: line 1149: X-Wmissing-prototypes: command not found ../libtool: line 1149: X-Wmissing-declarations: command not found ../libtool: line 1149: X-Wchar-subscripts: command not found ../libtool: line 1149: X-Wall: command not found ../libtool: line 1149: X-O2: command not found ../libtool: line 1149: Xi686-pc-linux-gnu-gcc: command not found ../libtool: line 1149: X-march=pentium4: command not found (...)
