>Description:
I'm using pkgsrc on a centos7 as user 
(./bootstrap/bootstrap --unprivileged --prefix=$HOME/.pkgsrc) and while trying to build editors/emacs26 with bmake install I get the following error 

/bin/grep: /scratch/balasr/pkgsrc/devel/gconfmm/work/.buildlink/gcc49/lib/../lib64/libstdc++.la: No such file or directory
/bin/sed: can't read /scratch/balasr/pkgsrc/devel/gconfmm/work/.buildlink/gcc49/lib/../lib64/libstdc++.la: No such file or directory
libtool:   error: '/scratch/balasr/pkgsrc/devel/gconfmm/work/.buildlink/gcc49/lib/../lib64/libstdc++.la' is not a valid libtool archive

This is the full log:

===> Installing dependencies for emacs26-26.1nb2
==========================================================================
The supported build options for emacs26 are:

	dbus gconf gnutls gtk gtk2 gtk3 imagemagick
	lucid motif nextstep svg x11 xaw xaw3d xft2
	xml

The currently selected options are:

	dbus gconf gnutls gtk3 svg x11 xaw3d xft2
	xml

You can select which build options to use by setting PKG_DEFAULT_OPTIONS
or the following variable.  Its current value is shown:

	PKG_OPTIONS.emacs (not defined)

==========================================================================
==========================================================================
The following variables will affect the build process of this package,
emacs26-26.1nb2.  Their current value is shown below:

        * CURSES_DEFAULT = curses
        * GAMEDATAMODE = 0644
        * JPEG_DEFAULT = jpeg
        * VARBASE = /home/msc18f22/.pkgsrc/var

Based on these variables, the following variables have been set:

        * CURSES_TYPE = curses
        * JPEGBASE (defined, but empty)
        * JPEG_TYPE = jpeg

You may want to abort the process now with CTRL-C and change their value
before continuing.  Be sure to run `/home/msc18f22/.pkgsrc/bin/bmake clean' after
the changes.

>How-To-Repeat:
Install pkgsrc as user:
./bootstrap/bootstrap --unprivileged --prefix=$HOME/.pkgsrc

Install emacs:
cd editors/emacs
bmake install
