Clearly it finds the correct include path (-ldb-4.2) and the correct function name (db_create_4002) but unfortunately it still attempts to use db_create (which is in the include path of sys-libs/db:4.5). I've fixed it locally by using sys-libs/db:4.5 but I guess it's supposed to be able to use db_create_4002 instead... As a side-note the elog in postinst() points to /usr/share/doc/${P}/${PN}-gentoo.readme.gz which is incorrect. Instead it should be /usr/share/doc/${PF}/${PN}-gentoo.readme* ($PF and may be any sort of compression..). # emerge -va1 courier-imap [...] [ebuild U ] net-mail/courier-imap-4.1.2-r1 [4.0.6-r2] USE="berkdb fam nls -debug -gdbm -ipv6 (-selinux)" 0 kB [...] checking for db_create_4004 in -ldb-4.4... no checking for db_create_4003 in -ldb-4.4... no checking for db_create_4002 in -ldb-4.4... no checking for db_create_4001 in -ldb-4.4... no checking for db_create_4000 in -ldb-4.4... no checking for db_create in -ldb-4.4... no checking for db_create_4004 in -ldb4.4... no checking for db_create_4003 in -ldb4.4... no checking for db_create_4002 in -ldb4.4... no checking for db_create_4001 in -ldb4.4... no checking for db_create_4000 in -ldb4.4... no checking for db_create in -ldb4.4... no checking for db_create_4004 in -ldb44... no checking for db_create_4003 in -ldb44... no checking for db_create_4002 in -ldb44... no checking for db_create_4001 in -ldb44... no checking for db_create_4000 in -ldb44... no checking for db_create in -ldb44... no checking for db_create_4004 in -ldb-4.3... no checking for db_create_4003 in -ldb-4.3... no checking for db_create_4002 in -ldb-4.3... no checking for db_create_4001 in -ldb-4.3... no checking for db_create_4000 in -ldb-4.3... no checking for db_create in -ldb-4.3... no checking for db_create_4004 in -ldb4.3... no checking for db_create_4003 in -ldb4.3... no checking for db_create_4002 in -ldb4.3... no checking for db_create_4001 in -ldb4.3... no checking for db_create_4000 in -ldb4.3... no checking for db_create in -ldb4.3... no checking for db_create_4004 in -ldb43... no checking for db_create_4003 in -ldb43... no checking for db_create_4002 in -ldb43... no checking for db_create_4001 in -ldb43... no checking for db_create_4000 in -ldb43... no checking for db_create in -ldb43... no checking for db_create_4004 in -ldb-4.2... no checking for db_create_4003 in -ldb-4.2... no checking for db_create_4002 in -ldb-4.2... yes checking for db_create_4004... no checking for db_create_4003... no checking for db_create_4002... yes checking for db_create_4001... no checking for db_create_4000... no checking for db_create... no [...] creating libbdbobj.la (cd .libs && rm -f libbdbobj.la && ln -s ../libbdbobj.la libbdbobj.la) /bin/sh ./libtool --tag=CXX --mode=link x86_64-pc-linux-gnu-g++ -march=k8 -pipe -O2 -ggdb -static -o testbdb testbdb.o libbdbobj.la -ldb-4.2 x86_64-pc-linux-gnu-g++ -march=k8 -pipe -O2 -ggdb -o testbdb testbdb.o ./.libs/libbdbobj.a /usr/lib64/libdb-4.2.so ./.libs/libbdbobj.a(bdbobj.o): In function `bdbobj_open': /var/tmp/portage/net-mail/courier-imap-4.1.2-r1/work/courier-imap-4.1.2/bdbobj/bdbobj.c:131: undefined reference to `db_create' collect2: ld returned 1 exit status make[3]: *** [testbdb] Error 1 make[3]: Leaving directory `/var/tmp/portage/net-mail/courier-imap-4.1.2-r1/work/courier-imap-4.1.2/bdbobj' make[2]: *** [all] Error 2 make[2]: Leaving directory `/var/tmp/portage/net-mail/courier-imap-4.1.2-r1/work/courier-imap-4.1.2/bdbobj' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/var/tmp/portage/net-mail/courier-imap-4.1.2-r1/work/courier-imap-4.1.2' make: *** [all] Error 2 * * ERROR: net-mail/courier-imap-4.1.2-r1 failed. * Call stack: * ebuild.sh, line 1654: Called dyn_compile * ebuild.sh, line 990: Called qa_call 'src_compile' * ebuild.sh, line 44: Called src_compile * courier-imap-4.1.2-r1.ebuild, line 165: Called die * * emake failed #

Experienced the same issue while having sys-libs/db-4.2.52_p4-r2 and sys-libs/db-4.5.20_p2 installed. Unmerging the db-4.2 version solved the problem.
chutzpah has taken over courier-imap maint.
4.5.0 picks the correct db version and compiles fine in this testcase (both db 4.2 and 4.5 installed), so FIXED with this version :)
