+
+  After security/clamav is updated to 1.5.0, some users report that build
+  fails as below.
+
+    /usr/ports/security/clamav/work/clamav-1.5.1/libclamav/others.c:623:23: error: use of undeclared identifier 'CERTSDIR'
+      623 |         cvdcertsdir = CERTSDIR;
+          |                       ^
+    1 warning and 1 error generated.
+    ninja: build stopped: subcommand failed.
+    *** Error code 1
+
+  The error seems to happen with following conditions.
+
+  * Non-base SSL stack is used. That is, in /etc/make.conf there is such
+    setting as 'DEFAULT_VERSIONS+=ssl=openssl'.
+  * Previous version (1.4.3) of clamav package is already installed.
+
+  If you face it, you can work around it by uninstalling current clamav
+  package first.
