[gentoo-alt] How to debug this?

[Al]

Hello,

when I execute " ebuild ncurses-5.7-r4.ebuild install" it always
terminates with the following error:

linking infotocap.exe to tic.exe
(cd /home/prefix/gentoo/var/tmp/portage/sys-libs/ncurses-5.7-r4/image//home/prefix/gentoo/usr/bin
&& ln -s `echo tic.exe|       sed 's/.exe$//'|sed 's,x,x,'|sed
's/$/.exe/'` `echo infotocap.exe| sed 's/.exe$//'|sed 's,x,x,'|sed
's/$/.exe/'`)
      3 [main] bash 2232 child_copy: linked dll data write copy
failed, 0x6CEC9000..0x6CED7A20, done 0, windows pid 2232, Win32 error
487
/home/prefix/gentoo/bin/bash: fork: retry: Resource temporarily unavailable

When I run the installation manually (taken from build.log) it goes through:

cd /home/prefix/gentoo/var/tmp/portage/sys-libs/ncurses-5.7-r4/work/narrowc/
make DESTDIR=/home/prefix/gentoo/var/tmp/portage/sys-libs/ncurses-5.7-r4/image/
install

One explenation I can imagine is, that the environment variables
inside the ebuild process are different.

I tried to compare both environments by a diff that I attach, but I
don't see the point.

Any idea how I could debug this in an efficiant way?

Thanks

Al
