ccache "make buildworld" fails (mmap problem?)

[Hashimoto]

Hello.
I have a problem about ccache.
I installed devel/ccache from ports.
"make buildworld" stopped immediately and failed.
In the ccache log file, I found the "Faild to mmap" message.

I also tried to reinstall devel/libtool15
following /usr/local/share/doc/ccache/cchace-howto-freebsd.txt .
But, again, it failed.

When I disable ccache, "make buildworld" & installing devel/libtool15
successfully finishes.

Any suggestions?
Regeards.
