cxsparse (an extended version of csparse, needed for octave) attempts to overwrite the /usr/include/cs.h file which is part of csparse. Reproducible: Always Steps to Reproduce: 1. emerge csparse 2. emerge cxsparse Actual Results: ... * This package will overwrite one or more files that may belong to other * packages (see list below). You can use a command such as `portageq * owners / <filename>` to identify the installed package that owns a * file. If portageq reports that only one package owns a file then do * NOT file a bug report. A bug report is only useful if it identifies at * least two or more packages that are known to install the same file(s). * If a collision occurs and you can not explain where the file came from * then you should simply ignore the collision since there is not enough * information to determine if a real problem exists. Please do NOT file * a bug report at http://bugs.gentoo.org unless you report exactly which * two packages install the same file(s). Once again, please do NOT file * a bug report unless you have completely understood the above message. * * Detected file collision(s): * * /usr/include/cs.h * * Searching all installed packages for file collisions... * * Press Ctrl-C to Stop * * sci-libs/csparse-2.2.1 * /usr/include/cs.h * * Package 'sci-libs/cxsparse-2.2.1' NOT merged due to file collisions. * If necessary, refer to your elog messages for the whole content of the * above message. ... Expected Results: cxsparse should have been emerged. I can't see any compelling reason why I shouldn't be able to have both packages together. $ emerge --info Portage 2.2_rc14 (default/linux/amd64/2008.0, gcc-4.3.2, glibc-2.8_p20080602-r0, 2.6.27-gentoo-r2 x86_64) ================================================================= System uname: Linux-2.6.27-gentoo-r2-x86_64-Intel-R-_Core-TM-2_Quad_CPU_Q9650_@_3.00GHz-with-glibc2.2.5 Timestamp of tree: Wed, 12 Nov 2008 22:45:01 +0000 app-shells/bash: 3.2_p39 dev-java/java-config: 1.3.7, 2.1.6-r1 dev-lang/python: 2.4.4-r13, 2.5.2-r8 dev-python/pycrypto: 2.0.1-r6 dev-util/cmake: 2.6.2 sys-apps/baselayout: 2.0.0 sys-apps/openrc: 0.3.0-r1 sys-apps/sandbox: 1.2.18.1-r3 sys-devel/autoconf: 2.13, 2.63 sys-devel/automake: 1.5, 1.9.6-r2, 1.10.1-r1 sys-devel/binutils: 2.19 sys-devel/gcc-config: 1.4.0-r4 sys-devel/libtool: 2.2.6a virtual/os-headers: 2.6.27-r2 ABI="amd64" ACCEPT_KEYWORDS="amd64 ~amd64" ALSA_CARDS="ali5451 als4000 atiixp atiixp-modem bt87x ca0106 cmipci emu10k1x ens1370 ens1371 es1938 es1968 fm801 hda-intel intel8x0 intel8x0m maestro3 trident usb-audio via82xx via82xx-modem ymfpci" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mmap_emul mulaw multi null plug rate route share shm softvol" APACHE2_MODULES="actions alias auth_basic authn_alias authn_anon authn_dbm authn_default authn_file authz_dbm authz_default authz_groupfile authz_host authz_owner authz_user autoindex cache dav dav_fs dav_lock deflate dir disk_cache env expires ext_filter file_cache filter headers include info log_config logio mem_cache mime mime_magic negotiation rewrite setenvif speling status unique_id userdir usertrack vhost_alias" ARCH="amd64" ASFLAGS_x86="--32" AUTOCLEAN="yes" CBUILD="x86_64-pc-linux-gnu" CDEFINE_amd64="__x86_64__" CDEFINE_x86="__i386__" CFLAGS="-march=nocona -O2 -pipe" CFLAGS_x86="-m32" CHOST="x86_64-pc-linux-gnu" CHOST_amd64="x86_64-pc-linux-gnu" CHOST_x86="i686-pc-linux-gnu" CLASSPATH="."

Thanks much for the note and I can confirm this. We can't really have them block each other since they are both pulled in by suitesparse at the moment. Is there actually any reason to have csparse around with cxsparse in the tree? As far as I know cxsparse is a superset of csparse but I may be wrong. Thanks, Markus
*** Bug 248326 has been marked as a duplicate of this bug. ***
Since csparse is more for educational purposes, I committed a fix to install its header in /usr/include/csparse. Please re-open if you see it as a problem.
