Bugzilla Bug 95603

When trying to emerge gtkscintilla2 it crashes due to the -fPIC error, but in
the ebuild the -fPIC CFLAG is set and it is used for compilation.

Reproducible: Always
Steps to Reproduce:
1. emerge gtkscintilla2
Actual Results:  
I ../include -I ../src  -c ../src/LexYAML.cxx

Tried to emerge with the addition of -fPIC in make.conf USE command, suggested
in forums.  No change and emerge failure at same point in compile.

Created an attachment (id=62932) [edit]
Escapes the slashed in the sed script.

It's a bug in the ebuild.
GTHREAD_LDFLAGS contains slashes and sed doesn't like that.
Maybe it's better to do it directly in the sed command (untested):
sed -e "/CFLAGS/s/-g/${CFLAGS} -fPIC/" \
	-e "s/^LDFLAGS_PRE =/LDFLAGS_PRE = $(echo ${GTHREAD_LDFLAGS} | sed
's|/|\\/|g')/" -i Makefile

Changing
GTHREAD_LDFLAGS="$(pkg-config gthread-2.0 --libs)"
to
GTHREAD_LDFLAGS=$(echo "$(pkg-config gthread-2.0 --libs)" | sed 's|/|\\/|g')

as Philipp suggests, allows compilation here

I'm fine to apply this, amd64 team - does this make sense (-fPIC help needed).

since this package only builds libraries (or well, one library ;)), it's fine
to
apply -fPIC to everything. fixed in cvs
